[0032] As Figure 1 shown, a method for drawing a Nightingale rose diagram according to this application includes the following operations:

[0033] S1. When receiving a command to draw a chart, obtain the data for drawing the chart and the basic parameters for drawing the chart; wherein, the chart is a Nightingale rose chart; the basic parameters of the chart include: the total number of data, the maximum value in the data, the chart position coordinates, the size parameters of the chart, and the angle parameters of the chart;

[0034] Among them, the total number of data refers to the number of data in the rose chart sectors or the number of data in the rose chart petals when drawing the chart;

[0035] The chart position coordinates refer to the position where the chart is inserted;

[0036] The outer circle size parameter of the chart refers to the maximum outer circle size of the chart, which can be the diameter of the outer circle or the radius of the outer circle;

[0037] The proportion of the inner circle refers to the proportion of the blank circular area inside the chart to the entire outer circle of the chart;

[0038] The starting angle of the graph corresponding to the first data refers to the starting angle of the graph corresponding to the data ranked first in the drawing order, which is used to determine the display mode of each graph in the optimal chart or the graph display mode desired by the user. This angle can be predetermined or determined according to the parameters input by the user;

[0039] The total angle of the chart means that all the graphs in the Nightingale rose chart are arranged in a 360-degree entire circumference as shown in Figure 3 or not arranged in the entire circumference, for example, arranged in 270 degrees as shown in Figure 6 shown.

[0040] S2. Draw each graph corresponding to the data obtained in the following manner:

[0041] S21. Determine the graph parameters for drawing the graph corresponding to the data according to the basic parameters for drawing the chart obtained and the value of the data; wherein, the graph parameters include: the outer circle size parameter, the position coordinates, the starting angle, and the ending angle.

[0042] S22. Draw the graph corresponding to the data according to the determined graph parameters; wherein, each graph corresponding to the data obtained is a sector in the Nightingale rose chart.

[0043] Among them, the outer circle size parameter refers to the radius or diameter of the top arc of the graph;

[0044] The position coordinates refer to the position coordinates of the upper left corner of the rectangle corresponding to the graph, which is used to determine that the graph is centered with all the graphs in the chart, as shown in Figure 7 shown;

[0045] The starting angle and the ending angle are used to define the position and proportion of the figure in the circumferential direction;

[0046] The inner circle size parameter refers to the proportion of the span from the outer circle to the inner circle to the diameter of the outer circle. Generally, the maximum is 0.5 (that is, the inner circle size is 0, and the span from the outer circle to the inner circle occupies the entire radius of the outer circle, but the value is 0.5, so it can be inferred that the software itself calculates the size of the inner circle as P * the diameter of the outer circle), and the minimum is 0 (that is, the inner circle coincides with the outer circle, and the span from the outer circle to the inner circle is 0).

[0047] In an exemplary embodiment, the basic parameters of the chart can be presented through a program to show a basic parameter setting interface for the user to input, or can be predefined according to experience.

[0049] Such as Figure 5 and Figure 6 As shown, the Nightingale rose chart is a chart composed of multiple arcs. Each data corresponds to a figure. By drawing the figures corresponding to each data, the Nightingale rose chart is obtained.

[0050] In an exemplary embodiment, each data corresponding figure is drawn by selecting a basic figure, such as a hollow arc. The various figure parameters of the basic figure are modified according to different data, so as to obtain the figures corresponding to each data.

[0055] In an exemplary implementation, the size parameters of the chart include the outer circle size of the chart; or, the size parameters of the chart include the outer circle size of the chart and the proportion of the inner circle.

[0056] Generally, in a program, regardless of how many degrees of the 360 degrees an arc occupies, in OFFICE programs, its diameter is equal to its width and height, that is, the diameter is the width and height. When drawing graphics in OFFICE and other office software, generally, the radius or diameter is not used to represent the size of an arc, but the width and height are commonly used. In the embodiments of the present application, using the outer circle size facilitates readers to understand what this size is. Additionally, it enables readers to understand that the drawn graphic must have a width equal to its height (width to height ratio of 1:1). Therefore, the R value calculated in the embodiments of the present application can be regarded as the diameter and also the length and width of the sector.

Specifically, the position of the cell can be directly taken as the chart position. In other embodiments, the chart position coordinates can be determined according to the cursor position, or can be determined by a pre-specified position, etc.

[0072] In an exemplary embodiment, when the angle parameter of the chart includes the total chart angle;

[0073] The starting angle is calculated by the following formula:

[0074]

[0076]

[0077] Wherein, CTA represents the total chart angle; C represents the total number of data; I represents the sequence number of the data; SA represents the starting angle of the figure; EA represents the ending angle;

[0078] When the angle parameter of the chart includes the total chart angle and the starting angle of the first data;

[0079] The starting angle is calculated by the following formula:

[0080]

[0096] The embodiments of the present invention provide various methods for drawing a Nightingale rose diagram, such as Figure 3 A Nightingale rose diagram without a blank area in the center, and Figure 6 A Nightingale rose diagram with a blank area, also provide a form arranged in a full 360-degree circle, and a form arranged in a non-full circle, and at the same time provide the user with the option to select the arrangement order of the figures.

[0097] When the user needs to draw a solid Nightingale rose chart, the proportion of the inner circle does not need to be obtained when acquiring the chart parameters; on the contrary, when a hollow Nightingale rose chart needs to be drawn, the proportion of the inner circle and the inner circle size parameters of each graph need to be obtained. When the user needs to draw a Nightingale rose chart arranged in a full circle or a non-full circle, the total angle of the chart needs to be set. When the user limits the display position of the graph in the circumferential direction, the starting angle of the graph corresponding to the first data of the graph basic parameters needs to be limited.

[0116]

[0117] It can be understood that subtracting 90 in the formula is because the 0 - degree of the hollow arc is at the 3 - o'clock direction of the clock, while the 0 - degree in common sense is at the 0 - o'clock direction of the clock. This is done to conform to common sense.

[0118] 106: Calculate and set the value EA of adjustment point 2 of S (i.e., the ending angle of the hollow arc), formula:

[0119]

[0120] 107: Calculate and set the value P of condition point 3 of S (i.e., the size of the inner circle of the hollow arc), formula:

[0121]

[0122] 108: Judge whether I mod 6 = 0 holds; if yes, calculate and set the color number CI of the color matching scheme to be filled in S, formula: CI = 10; if not, calculate and set the color number CI of the color matching scheme to be filled in S, formula: CI = I mod 6 + 4;

[0123] 109: Judge whether I / 6 > 0 holds; if yes, continue with the following steps;

[0124] 110: Calculate and set the brightness value L of the filling color of S, formula:

[0125]

[0126] 111: Set the border color of graphic S to color number 1 of the color matching scheme;

[0127] 112: Calculate and set the value of variable I, formula: I = I + 1;
