Example one
Label display is performed on the highlight selected point in fig. 2, the width of the canvas of the graph is 820, the height of the canvas is 610, in the embodiment, the coordinate origin of the canvas is at the upper left corner, the right direction of the X axis is the positive direction of the X axis, and the downward direction of the Y axis is the positive direction of the Y axis; the offset distance L is set to 40 and the angle r increases by 5 ° per rotation. The specific process is as follows:
first, the center point (O) of the position of all the target data points is calculated, with coordinates (389, 209), marked by the five-pointed star in fig. 2;
next, the label is placed starting with the target data point (a) closest to the center point. The coordinate of the position of the A point is (398, 208), and the position is positioned at the upper right of the central point, so that Ai (438, 168) is calculated according to (X + L, Y-L) and is used as the initial position of the label of the target data point (A). If there is no overlap between the labels and the rest of the target data points are not covered, Ai is the position of the label of the target data point (a), which can be specifically referred to in fig. 3.
Then, when calculating the position of the next data point (B), the position coordinate of the B point is (381, 212), and since the target data point is left and below the center point, the initial point Bi (341, 251) can be obtained according to (X-L, Y + L), as shown in FIG. 4, and the initial label covers part of the target data point.
And calculating according to the Bi position to obtain the radius step length r of 12. The initial point position is taken as the center of a circle, R =12 is taken as the radius, the positive direction of the X axis is taken as the initial edge, the rotation is carried out for 5 degrees every time, the anticlockwise rotation is carried out for one circle, and at the moment, the label still covers part of other target data points. Then, overlap removing treatment is carried out: the effective position of the label at which point B is finally obtained after rotating counterclockwise by 40 ° from the horizontal direction with R =24 as the radius from the center of Bi is (358, 268). As shown in fig. 5, there is no overlap between the labels at this time and no other target data points are obscured.
By analogy, the effect of placing tags for 20 target data points can be seen in FIG. 6.
Finally, the label positions of all the target data points are finally calculated and displayed, and the effect can refer to fig. 7.
Through the embodiment, the displayed labels are reasonably distributed, other target data points are not covered, and the condition that the labels are mutually overlapped does not occur. However, if the label displaying the data points in the above embodiment is selected, the label position is not subjected to de-overlapping processing, the displaying effect can refer to fig. 8, and it is obvious that a large amount of displayed labels are overlapped due to too many selected data points, so that label information displaying is affected, even the selected data points are covered, and the displaying effect is greatly affected. The comparison shows the effect of the label display method of the embodiment.
The invention also discloses a chart label display system which comprises a storage device, wherein a plurality of instructions are stored in the storage device, and the instructions are suitable for being loaded by the processor and executing the chart display method.
In summary, the invention designs the placing position of the label by taking the central point of the target data point as a reference and adopting a spiral outward expansion mode, thereby realizing the overlap removal. On the one hand, can avoid the label to appear overlapping to the at utmost, on the other hand can make the even and non-overlapping distribution of label around the point, furthest utilizes the show space in the diagram, has promoted user experience.
Finally, it should be noted that the above-mentioned list is only a specific embodiment of the present invention. It is obvious that the present invention is not limited to the above embodiments, but many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
