With successive clicks on a button, the quadrants of the circle with different colors will appear, of course, using canvas and arc

You should be using "set Canvas1.PaintColor", not "set Canvas1.LineWidth".

Hello and thanks . But why are the percentage numbers not exactly on their respective parts and are scattered?In addition, in some programs, the value of the parts of the pie chart is not fixed and changes.

[NishyanthKumar]

The formula to calculate the angle is also incorrect.

The image on the top is Tim's code, the one on the bottom is that of yours.
The error lies in which part of the code is surrounded by the "divide by two" blocks.

Hello and thanks again . I'm sorry that I didn't pay attention to these point.

Hello again, is it possible to change the font of these texts inside the canvas?

[NishyanthKumar]

Note that you might want to tweak with the x and y positions of the bigger text, since they may seem off-centered.

Hello and thanks again, font type?For example, let's convert the numbers inside the pie graph to Persian font.

You could try using this:

MyFonts → use your own custom fonts (a modified version of @Ken's YourFont extension)

Here is a modified version of @Ken's extension "YourFont". YourFont doesn't work with Companion (on devices with Android > 9) since the AI2 nb184 release. See also here: Error in YourFont Extension - #20 by Anke

Example - blocks

Note that you need a .ttf file for the extension to function.

Hello and thanks, unfortunately this extension cannot be used for Canvas.

Can you paste Persian font digits into text blocks?

Then it would be possible to loop through the characters of a text representation of a number, replacing the digits with their Persian equivalents.

If you prepare a text file in Persian with 100 lines, having line n contain the Persian text representation of number n, you could load it from the Media folder at screen Initialize, and split it into a global list of number strings, available for a Select item n from List block for your Canvas DrawText input.
