Android : canvas.drawBitmap() method not working properly

Question

I already post two question related this (plz refer this custom piechart 1 and this custom pie chart 2) but not getting answer ,finally i develop my own but getting stuck at so

Answer 1

Thanks to every one. finally i did it using replacing this stuff Rotating Image on A canvas

 matrix.postRotate(_angle1);    
 canvas.drawBitmap(myBitmap1, matrix, null);

with this

Matrix matrix1 = new Matrix();
matrix1.setRotate(_angle1, 0, 0);
canvas.drawBitmap(myBitmap1, matrix1, null);

here ,first you should change the value like this ,

 float myAngle = 0;
 myAngle = ((90 * values.get(i)) / 16);
