With our latest service release we introduced a few new features to the IGPieChartView which I figured I would give a little demonstration of.
Exploding Slices - Extended Radius
The IGPieChartView released with exploding slices, which would pop the slice away from the center radius of the chart.
With the lastest SR, we introduced a second mode that was requested by a customer. In this mode the slice will not pull away from the center, but instead increase it's outer radius to highlight itself.
// New feature # 1 : Slice explosion, extended radius.
// When doing a slice explosion, the default is to move the slice out from the center of the pie chart.
// Instead we can have the chart extend the radius of the "exploded" slice.
_pie.allowSliceExplosion = YES;
_pie.explodedDisplayStyle = IGPieSliceExplodedDisplayStyleExtendRadius;
Rotating Pie Chart
The second feature added were a pair of methods that allow you to programmatically spin the pie chart to have a slice start at a certain angle.
Sample project showing this in action
pieChartView rotateSliceWithDataPoint: toAngle: duration: alignment:
pieChartView rotateSliceWithIndex: toAngle: duration: alignment:
So that's it for this installment. As I mentioned briefly earlier, these features were requested by a customer. If you have a request for a feature in our frameworks, please let us know and we will see what can be done.
