Setting startAngle negative creates problems for insideAngle #308

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create a pie chart, set the startAngle to -90
2. Add a click listener.
3. Tap on the first pie slice (in the 0-90 degrees angle range).

What is the expected output? What do you see instead?
chartView.getCurrentSeriesAndPoint() returns null, no slice is matched.

Please provide a source code snippet that we can use to replicate the issue.

What version of the product binary library are you using?
1.1.0

Please provide any additional information below.
Simple workaround is to use positive startAngle, ie 270 instead of 90
