Pie chart are not clickable with large segment

[messenger63]

Hi, there is issue with Pie Chart.
Steps to reproduce:

• open sample app;
• set segments, like 8, 1, 1;
• run app, click on small segment, then click on large segment at 0 degree (at the beginning of segment on the screen);
  Results: clicks are not working, there is some issue in segment calculation.

Seems like this issue happens when you have large segment, single segment more than 180deg, then part of that segment at the beginning are not clickable.

Please, reply if this issue could be fixed in near future.

The issue is in calculating dist at PieRenderer.getContainingSegment()
Probably it should be something like this:

double dist = signedDistance(offset, angle);
double endDist = signedDistance(offset, lastOffset);
if (dist < 0) { // added
dist = FULL_PIE_DEGS + dist; // added
} // added
if(endDist < 0) {
// segment accounts for more than 50% of the pie and wrapped around
// need to correct:
endDist = FULL_PIE_DEGS + endDist;
}
Or some fix for signedDistance() method calculations.
