Multiple negative-able values in Stack bar chart

Scenario
Multiple negative-able values in one ChartDataSet.

Stack bar chart should be drawn with positive bars first, then the negative ones. Instead, it's drawn in the order of their indexes. The result is undefined when trying to draw negative value before a positive one.

Example:
BarChartDataEntry.values = [1, 1, -1, 1], colors = [red, green, yellow, black]
In this case, the yellow stack should be drawn below the xaxis, while black stack should be the one on top of it.
