I am busy wrapping this Github project. Attached is the Pie Chart functionality of the project/library. Posting the B4A project and Library files. Copy the library files to your additional library folder.
Some remarks about the Pie Chart:
1. It will display the values passed as a percentage of the total of the values that you pass
2. There are 3 x arrays that are passed to the library. Ensure that you pass the same number of elements in each of the arrays.
3. When you click on a pie slice the slice will increase in radial size (see pics below)
4. If you click on the radial increased slice it will return to normal size.
5. You can spin the pie chart around its centre point (CW and ACW) with your finger.
Untouched ...
Green slice touched ...
Pie Chart rotated with finger...
Some sample code:
