This library contains simple ways to create a pie chart with basic interaction and labels.
Steps to Implement
- Calculate the percentage of the values.
- We can find sweep angle with percentage.
- Add the current pie slice sweep angle with previous pie slice end angle.
- Create new pie slice view with start angle and sweep angle (Make sure to apply a different color for each pie splice).
Iterate all the points and calculate the angle and add pie slice to the layout.
total = 0; for (int i = 0; i < data.length; i++) { total += data[i]; } float startAngle = 0, sweepAngle;
