md` First, I named the data "ticks". And I made a table of the scale line values. If you use the sequence type of ransform, you can set the start value, end value, and determine the interval between the values in step, and it will automatically calculate and create a table of values. Start at 0 and go to the (maximum value - minimum value) + 0.1. The reason for adding 0.1 is that the final value itself is not included in the value. The scale line interval was calculated by dividing the difference between the maximum and minimum values by one less than the number of scale lines. Next, I set the following four formula types: "data_2": If the minimum value does not start with 0, there will be a gap between the ticks data and the value displayed on the scale. I filled that gap by adding a minimum to the data. To find the point on the arc, I calculated using trigonometric functions. "radianRef": Each ticks data was divided by the difference between the maximum and minimum values (this gives the percentage of the total value) and multiplied by π. This could have been written directly in the calculation of the points on the x and y axes in formula, but I chose this way because I wanted to simplify the calculation itself. I calculate the (x, y) coordinates of a point on an arc. However, here I want to display the value slightly below the ticks line, so I will make fine adjustments in the calculation. "x": The value of x can be calculated by r times cosθ, but I do not want to display it at the same position as ticks, so I subtracted 60% of the difference between outerRadiusw and innerRadius from outerRadius. Then, centerX - (calculation formula) is used because the x-axis at the center of the circle has centerX instead of 0. Also, if centerX + (calculation formula) is used, the display of ticks will not change from minimum to maximum, but will change from maximum to minimum. "y": The value of y can be calculated by r times sinθ, but the display position was adjusted as in the case of x. Then, centerY - (calculation formula) is used because the y-axis at the center of the circle is centerY. Also, if you set centerY + (calculation formula), the value of ticks will be displayed upside down. ### Scales `
