Pie chart does not work well with separate animations on x and y axis simultaneously

[liuxuan30]

Got this issue on SO:http://stackoverflow.com/questions/32970306/piechart-for-ios-charts-broken-in-swift-2-0/32982328#32982328

Demo project is also in that post, you may need to add Charts framework on your side manually to get it work (it is using Pods)

The issue is the pie chart is using two animate at the same time like below:

pieChartView.animate(xAxisDuration: 1.5, easingOption: ChartEasingOption.EaseOutBack)
pieChartView.animate(yAxisDuration: 1.5, easingOption: ChartEasingOption.EaseOutBack)

We do have a method to animate both axis:

pieChartView.animate(xAxisDuration: 1.5, yAxisDuration: 1.5, easingOption: ChartEasingOption.EaseOutBack)

Just want to double check, is it allowed to use two animate() on x and y axis at the same time? If so, then we have a bug here.

BTW, the author mentioned it is fine before swift 2.0 merged into master, not sure what animation logic changed since then

Actually I encountered this two days ago and haven't had the chance yet to fix it.
The second call should abort the first one, but for some reason it does not reset its phase variable.

Actually the second call aborts the first one - but it shouldn't. As the behaviour on the Android allows one to start after the other (to potentially delay the second animation to the middle of the first one)

[danielgindi]

I'll look into this later, and replace the stop() call with an update to the animation variables.

@danielgindi how this should work? User adding multiple animate() are allowed? Just keep the first animation?
