Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The information display method provided by each embodiment of the invention can be realized by electronic equipment with image processing and display functions. The electronic device may be a smartphone, a tablet computer, an e-book reader, a laptop portable computer, and the like.
For the sake of simplifying the description, the information display method is only exemplified below as being performed by an electronic device having a picture processing and display function, but this is not a limitation.
Referring to fig. 2, a flowchart of a method of displaying information according to an embodiment of the invention is shown. The method comprises the following steps:
the target direction may be any one of an up direction, a down direction, a left direction, and a right direction of the electronic device. Since electronic devices are typically scrolling up and down, the target direction is illustrated as an up direction.
in summary, the information display method provided in this embodiment generates a pie chart including n sector blocks and a description frame corresponding to each sector block according to n items of data; adjusting the description frame to be far away from the target direction; displaying a pie chart and a description frame through a display component; the problem that the display space of a mobile phone screen is limited, and when the distribution of a description frame is scattered and random, the display space can be wasted or the display cannot be fully displayed is solved; the method achieves the effect of regularly arranging the positions of the description frames, and enables the description frames positioned on one side of the target direction to be as few as possible, thereby saving the display space.
In particular implementations, the electronic device can adjust the description box in at least one of the following two ways. Firstly, the electronic equipment adjusts the sector block of the pie chart at one side of the target direction to be minimum; secondly, the electronic device adjusts the description frame belonging to one side of the target direction to be far away from the target direction, so that the purposes of saving the display space and improving the utilization rate of the space are achieved. An embodiment will be described below.
Referring to fig. 3, a flowchart of a method for displaying information according to another embodiment of the invention is shown. The method comprises the following steps:
Before generating the pie chart, a rectangular plane coordinate system XOY shown in fig. 4 is first determined, in which the right half axis of the X axis is a positive half axis, the lower half axis of the Y axis is a positive half axis, and a concentric circle 41 and a concentric circle 42 are made with O as the center. It should be noted that, the plane rectangular coordinate system XOY may also be determined by taking the left half axis of the X axis as a positive half axis, and the upper half axis of the Y axis as a positive half axis, etc., and this embodiment is only described by taking the plane rectangular coordinate system XOY as the plane rectangular coordinate system shown in fig. 4, and does not limit the embodiment of the present invention.
The electronic equipment can sort the n items of data according to the proportion of each item of data in the total sum of the data and sequentially allocate a corresponding sector area to each item of data according to the sorting result. In order to ensure the display effect, it is reasonable that the data items are 2-4 items of data. Step 301 may include the following sub-steps:
the electronic equipment calculates the proportion of each item of data in the total sum of the data;
for example, if 4 items of data are included in total, where data a is 5, data B is 10, data C is 15, and data D is 20, the sum of the data is 50, and the ratio of data a is calculated to be 10%, the ratio of data B is 20%, the ratio of data C is 30%, and the ratio of data D is calculated to be 40%.
Secondly, the electronic equipment sorts the n items of data according to the proportion of each item of data in the total sum of the data;
the electronic device sorts the n items of data from small to large or from large to small according to the calculated proportion of each item of data in the total sum of data, and this embodiment exemplifies the sorting from small to large, and is not limited to this.
Thirdly, the electronic equipment calculates the central angle of the sector block corresponding to each item of data according to the proportion corresponding to each item of data;
for example, in 4 items of data in total, the proportion of the data a is 10%, the proportion of the data B is 20%, the proportion of the data C is 30%, and the proportion of the data D is 40%, which are obtained by calculation, the central angle of the sector block corresponding to the data a is 36 °, the central angle of the sector block corresponding to the data B is 72 °, the central angle of the sector block corresponding to the data C is 108 °, and the central angle of the sector block corresponding to the data D is 144 °
And fourthly, the electronic equipment divides the sector blocks according to the central angle obtained by calculation to generate a pie chart.
The electronic device divides the sector blocks in the order from small to large from the positive X-axis direction and clockwise according to the size of each item of data, and generates a pie chart as shown in fig. 5.
It should be noted that, in an actual implementation process, in order to ensure the sequentiality of the data, when the data cannot be sorted in some embodiments, the electronic device may respectively calculate the proportion of each item of data in the total sum of the data and allocate a corresponding sector area to each item of data according to the proportion, that is, step two may be omitted, and only substeps one, three, and four need to be performed.
In step 302, a description box is generated for each sector.
In order to clearly and intuitively display the data attribute name of each item of data and the proportion of each item of data in the data sum, a description box is required to be added at the sector block corresponding to each item of data for adding description characters, wherein the description characters can be the data attribute name of each item of data, the proportion of each item of data in the data sum, and the like.
As one possible implementation, the electronic device may generate a description box for each sector based on the centerline of each sector.
After the central line of the sector block extends for a preset length outside the pie chart, the electronic equipment adds a description frame at the tail end of the central line according to the data attribute names corresponding to the sector block.
Referring to fig. 6, after the electronic device extends the center line 62 of the sector 61 by a predetermined length outside the pie chart, a description frame 63 is added to the end of the center line 62 according to the data attribute name corresponding to the sector 61.
In a specific implementation process, the electronic device may adjust the description frame away from the target direction in any one or two ways.
Firstly, the electronic equipment enables the sector area on one side of the target direction to be minimum through rotation operation according to the preset target direction.
And secondly, the electronic equipment adjusts the description frame belonging to one side of the target direction to be far away from the target direction.
For the first of these:
the target direction may be any one of an up direction, a down direction, a left direction, and a right direction of the electronic device. Since electronic devices are typically scrolling up and down, the target direction is illustrated as an up direction.
The term "one side of the target direction" refers to a space that divides the pie chart into two equal sides according to a straight line perpendicular to the target direction and belongs to one side of the target direction. If the target direction is the upper direction, the space belonging to one side of the upper direction is the 'target direction side' after dividing the pie chart into two equal sides according to a horizontal straight line.
The present embodiment is only illustrated with the target direction as the upper direction, and the present invention is not limited to the above embodiment, and the present step may include the following sub-steps:
1. the electronic equipment selects two sector blocks with the largest sum of central angles from every two adjacent sector blocks in the pie chart;
the electronic equipment obtains the central angle corresponding to each sector block in the pie chart, respectively calculates the sum of the central angles corresponding to two adjacent sector blocks, and selects the two sector blocks with the largest central angle sum.
It should be noted that the electronic device may also obtain two corresponding sector blocks by selecting two items of data with the largest sum of the proportions of two adjacent items of data, which is not limited in this embodiment.
2. The electronic equipment rotates the pie chart to enable the two fan-shaped blocks to be located on one side of the target direction, and the central line determined according to the two fan-shaped blocks is overlapped with the target direction.
As shown in fig. 7A, the pie chart 71 is divided into 4 sectors, and when the adjacent sectors 72 and 73 are two sectors having the largest sum of central angles among every two adjacent sectors, the central line determined from the sectors 72 and 73 coincides with the target direction by rotating the pie chart 71.
In addition, there is a possible case where, when the central angle of the largest sector in the pie chart is larger than the first angle, which may be 180 °, the electronic device may rotate the pie chart so that the largest sector is located on the side of the target direction and the center line of the largest sector coincides with the target direction, thereby minimizing the sectors on the side of the target direction.
As shown in fig. 7B, the central angle corresponding to the sector 74 is greater than 180 °, and the electronic device only needs to rotate the pie chart to locate the sector 74 at one side of the target direction, and the central line of the sector 74 coincides with the target direction, so that the sector located at one side of the target direction can be minimized.
For the second of these:
the electronic device adjusts the description frame on one side of the target direction to make the description frame far away from the target direction, so as to save the display space of the target direction, and the step may include the following substeps:
1. when the description frame is generated based on the center line of the sector block, the description frame corresponding to the sector block having an angle of less than 90 ° between the center line of the sector block and the target direction is determined as the description frame belonging to the target direction side.
As shown in fig. 7C, the description box 75 and the description box 76 are description boxes generated based on the center line of the sector, and the included angle between the center line of the sector corresponding to the description box 75 and the description box 76 and the target direction is less than 90 °, that is, the description box 75 and the description box 76 may be determined as description boxes belonging to one side of the target direction.
2. And bending a connecting line between the description frame and the pie chart which belong to one side of the target direction to the opposite direction of the target direction, wherein the included angle between the bent connecting line and the target direction is a second angle which is larger than 90 degrees.
Taking the second angle as 120 ° as an example, as shown in fig. 7C, the description frame 75 and the description frame 76 belong to one side of the target direction, a connecting line between the description frame 75 and the pie chart is bent in the opposite direction of the target, and an included angle between the bent connecting line and the target direction is 120 °; similarly, it will be described that the line between the frame 76 and the pie chart is bent in the opposite direction to the target, and the angle between the bent line and the target direction is 120 °.
It should be noted that the second angle may be preset according to the size of the screen, and the embodiment is described by taking the second angle as 120 ° as an example, and is not limited to the embodiment of the present invention.
In the implementation process, the description frames may overlap with each other, so the positions of the description frames need to be adjusted. This step may include the following substeps:
firstly, the electronic equipment selects a description frame to obtain the position of the current description frame;
secondly, the electronic equipment acquires the positions of two adjacent description frames of the current description frame;
if the current description frame and one of the description frames are mutually covered and separated from the other description frame, the electronic equipment finely adjusts the preset angle of the current description frame to the direction of the separated description frame according to the circumferential path;
the electronic equipment judges whether the current description frame and the two adjacent description frames are mutually covered or not according to the position relation of the current description frame and the two adjacent description frames. When the current description frame and one of the description frames are mutually covered and separated from the other description frame, the electronic equipment finely adjusts the current description frame to the direction of the description frame separated from the current description frame by a preset angle according to the circumferential path.
And fourthly, repeating the substeps one to three until all the description frames are not covered.
Then, the electronic device may display the pie chart as follows:
and step 304, initializing a circumscribed rectangle frame of the pie chart into a cutting frame.
The electronic equipment acquires a circumscribed rectangle of the pie chart, four edges of the circumscribed rectangle are respectively tangent to the circumference of the pie chart, and the circumscribed rectangle is initialized into a cutting frame.
Referring to FIG. 8, the electronic device initializes the circumscribed rectangle 82 of the pie chart 81 to a cropped border.
In step 305, it is determined whether each description box is located in a clipping border.
The electronic equipment acquires the vertical coordinates of the upper boundary and the lower boundary of the cutting frame and the horizontal coordinates of the left boundary and the right boundary. Then, the electronic equipment acquires the vertical coordinates of the upper boundary and the lower boundary of each description frame and the horizontal coordinates of the left boundary and the right boundary, and when the vertical coordinate of the upper boundary of each description frame is larger than the vertical coordinate of the upper boundary of the cutting frame, the vertical coordinate of the lower boundary of each description frame is smaller than the vertical coordinate of the lower boundary of the cutting frame, the vertical coordinate of the left boundary of each description frame is larger than the vertical coordinate of the left boundary of the cutting frame, and the vertical coordinate of the right boundary of each description frame is smaller than the vertical coordinates of the cutting frame and the boundary, the description frame is located in the cutting frame.
And step 306, when the description frame is positioned outside the clipping frame, enlarging the clipping frame according to the description frame.
When the description box is not clipped in the frame, the electronic equipment enlarges the clipped frame according to the description box.
Step 306 may include the following sub-steps:
the method comprises the steps that firstly, the electronic equipment obtains the minimum value of the vertical coordinate of the upper boundary and the horizontal coordinate of the left boundary of a description frame and a cutting frame, and the maximum value of the vertical coordinate of the lower boundary and the horizontal coordinate of the right boundary;
and secondly, expanding the cutting frame by the electronic equipment according to the minimum value of the upper boundary ordinate and the left boundary abscissa, and the maximum value of the lower boundary ordinate and the right boundary abscissa.
The electronic equipment determines the vertical coordinate of the upper boundary of the enlarged cutting frame according to the minimum value of the vertical coordinate of the upper boundary between the description frame and the cutting frame; the electronic equipment determines the left boundary abscissa of the enlarged clipping frame according to the minimum value of the left boundary abscissas of the description frame and the clipping frame; the electronic equipment determines the lower boundary ordinate of the enlarged clipping frame according to the maximum value of the lower boundary ordinate of the description frame and the clipping frame; and the electronic equipment determines the right boundary abscissa of the enlarged clipping frame according to the maximum value of the right boundary abscissas of the description frame and the clipping frame.
As shown in fig. 8, an enlarged cropping frame upper boundary 83 determined from the minimum value of the description frame and cropping frame upper boundary ordinate, an enlarged cropping frame left boundary 84 determined from the minimum value of the description frame and cropping frame left boundary abscissa, an enlarged cropping frame lower boundary 85 determined from the maximum value of the description frame and cropping frame lower boundary ordinate, and an enlarged cropping frame right boundary 86 determined from the maximum value of the description frame and cropping frame right boundary ordinate. The upper border 83, left border 84, lower border 85 and right border 86 form an enlarged crop frame.
And 307, cutting out the pie chart and the description frame according to the cutting frame when each description frame is positioned in the cutting frame.
As shown in fig. 8, the electronic device cuts out the pie chart and the description frame according to the cutting border 87, and the pie chart and the description frames are located in the cutting border 87.
The electronic device displays the cut pie chart and the description frame through the display component, and the display effect is as shown in fig. 9. The display component can be a display card device or a display chip.
It should be noted that the electronic device may adjust the description frame to be away from the target direction by executing any one or two methods in step 303 to achieve the purposes of saving the display space and improving the utilization rate of the space.
In summary, the information display method provided in this embodiment generates a pie chart including n sector blocks and a description frame corresponding to each sector block according to n items of data; adjusting the description frame to be far away from the target direction; displaying a pie chart and a description frame through a display component; the problem that the display space of a mobile phone screen is limited, and when the distribution of a description frame is scattered and random, the display space can be wasted or the display cannot be fully displayed is solved; the method achieves the effect of regularly arranging the positions of the description frames, minimizing the description frames positioned on one side of the target direction and saving the display space.
In the embodiment, the pie chart is rotated, so that the fan-shaped blocks of the pie chart on one side of the target direction are minimized, and the effect of saving the display space of the target direction is achieved.
In this embodiment, the connecting line between the description frame belonging to the target direction side and the pie chart is bent in the opposite direction to the target direction, so that the position of the description frame on the target direction side is adjusted in the opposite direction to the target direction, and the display space in the target direction is saved.
In the embodiment, the external rectangle of the pie chart is initialized to the cutting frame, and is expanded along with the cutting frame according to the description frame, and when each description frame is positioned in the cutting frame, the pie chart and the description frame are cut according to the cutting frame, so that the effect of saving the display space is achieved.
As a preferred embodiment, the pie chart may be adjusted before adding the description frame, so that the sector area of the pie chart on the side of the target direction is minimized, and then the description frame may be added and the description frame on the side of the target direction may be adjusted. An embodiment will be described below.
Referring to fig. 10, a flowchart of a method for displaying information according to another embodiment of the invention is shown. The method comprises the following steps:
Before generating the pie chart, a rectangular plane coordinate system XOY shown in fig. 4 is first determined, in which the right half axis of the X axis is a positive half axis, the lower half axis of the Y axis is a positive half axis, and a concentric circle 41 and a concentric circle 42 are made with O as the center. It should be noted that, the plane rectangular coordinate system XOY may also be determined by taking the left half axis of the X axis as a positive half axis, and the upper half axis of the Y axis as a positive half axis, etc., and this embodiment is only described by taking the plane rectangular coordinate system XOY as the plane rectangular coordinate system shown in fig. 4, and does not limit the embodiment of the present invention.
The electronic equipment can sort the n items of data according to the proportion of each item of data in the total sum of the data and sequentially allocate a corresponding sector area to each item of data according to the sorting result. In order to ensure the display effect, it is reasonable that the data items are 2-4 items of data. Step 301 may include the following sub-steps:
the electronic equipment calculates the proportion of each item of data in the total sum of the data;
for example, if 4 items of data are included in total, where data a is 5, data B is 10, data C is 15, and data D is 20, the sum of the data is 50, and the ratio of data a is calculated to be 10%, the ratio of data B is 20%, the ratio of data C is 30%, and the ratio of data D is calculated to be 40%.
Secondly, the electronic equipment sorts the n items of data according to the proportion of each item of data in the total sum of the data;
the electronic device sorts the n items of data from small to large or from large to small according to the calculated proportion of each item of data in the total sum of data, and this embodiment exemplifies the sorting from small to large, and is not limited to this.
Thirdly, the electronic equipment calculates the central angle of the sector block corresponding to each item of data according to the proportion corresponding to each item of data;
for example, in 4 items of data in total, the proportion of the data a is 10%, the proportion of the data B is 20%, the proportion of the data C is 30%, and the proportion of the data D is 40%, which are obtained by calculation, the central angle of the sector block corresponding to the data a is 36 °, the central angle of the sector block corresponding to the data B is 72 °, the central angle of the sector block corresponding to the data C is 108 °, and the central angle of the sector block corresponding to the data D is 144 °
And fourthly, the electronic equipment divides the sector blocks according to the central angle obtained by calculation to generate a pie chart.
The electronic device divides the sector blocks in the order from small to large from the positive X-axis direction and clockwise according to the size of each item of data, and generates a pie chart as shown in fig. 5.
It should be noted that, in an actual implementation process, in order to ensure the sequentiality of the data, when the data cannot be sorted in some embodiments, the electronic device may respectively calculate the proportion of each item of data in the total sum of the data and allocate a corresponding sector area to each item of data according to the proportion, that is, step two may be omitted, and only substeps one, three, and four need to be performed.
The electronic equipment minimizes the sector area on one side of the target direction through rotation operation according to the preset target direction.
Note that the target direction may be any one of an up direction, a down direction, a left direction, and a right direction of the electronic apparatus. Since electronic devices are typically scrolling up and down, the target direction is illustrated as an up direction.
The term "one side of the target direction" refers to a space that divides the pie chart into two equal sides according to a straight line perpendicular to the target direction and belongs to one side of the target direction. If the target direction is the upper direction, the space belonging to one side of the upper direction is the 'target direction side' after dividing the pie chart into two equal sides according to a horizontal straight line.
The present embodiment is only illustrated with the target direction as the upper direction, and the present embodiment is not limited thereto, and the step 1002 may include the following sub-steps:
the method comprises the steps that firstly, the electronic equipment selects two sector blocks with the largest sum of central angles from every two adjacent sector blocks in a pie chart;
the electronic equipment obtains the central angle corresponding to each sector block in the pie chart, respectively calculates the sum of the central angles corresponding to two adjacent sector blocks, and selects the two sector blocks with the largest central angle sum.
It should be noted that the electronic device may also obtain two corresponding sector blocks by selecting two items of data with the largest sum of the proportions of two adjacent items of data, which is not limited in this embodiment.
And secondly, the electronic equipment rotates the pie chart to enable the two fan-shaped blocks to be positioned at one side of the target direction, and the central line determined according to the two fan-shaped blocks is superposed with the target direction.
As shown in fig. 7A, the pie chart 71 is divided into 4 sectors, and when the adjacent sectors 72 and 73 are two sectors having the largest sum of central angles among every two adjacent sectors, the central line determined from the sectors 72 and 73 coincides with the target direction by rotating the pie chart 71.
In addition, there is a possible case where, when the central angle of the largest sector in the pie chart is larger than the first angle, which may be 180 °, the electronic device may rotate the pie chart so that the largest sector is located on the side of the target direction and the center line of the largest sector coincides with the target direction, thereby minimizing the sectors on the side of the target direction.
As shown in fig. 7B, the central angle corresponding to the sector 74 is greater than 180 °, and the electronic device only needs to rotate the pie chart to locate the sector 74 at one side of the target direction, and the central line of the sector 74 coincides with the target direction, so that the sector located at one side of the target direction can be minimized.
In step 1003, a description box is generated for each sector.
In order to clearly and intuitively display the data attribute name of each item of data and the proportion of each item of data in the data sum, a description box is required to be added at the sector block corresponding to each item of data for adding description characters, wherein the description characters can be the data attribute name of each item of data, the proportion of each item of data in the data sum, and the like.
As one possible implementation, the electronic device may generate a description box for each sector based on the centerline of each sector. At this time, step 1003 may include the following sub-steps:
for any sector block, the electronic equipment detects whether an included angle between the central line of the sector block and the target direction is smaller than a third angle;
because there are two included angles between the center line of the sector block and the target direction, and the sum of the two included angles is 360 °, the included angle referred to in this embodiment refers to the smaller included angle of the two included angles.
Referring to fig. 11, an angle between a center line 1102 of a sector 1101 and the target direction is α 1, and a third angle is an angle between the target direction and the sideline 1103, and the electronic device determines a magnitude relationship between the angle α 1 and the third angle, where the third angle may be 45 °.
When the angle is not smaller than the third angle, the electronic equipment extends the center line of the sector block to a preset length outside the pie chart, and then adds a description frame at the tail end of the center line according to the data attribute name corresponding to the sector block;
