CandleStickChartRenderer drawDataSet method does not work with CombinedChartView

[smwallace]

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

ℹ Created a CombinedChartView with a CandleStickChartRenderer to draw the candlesticks.

What did you expect to happen?

ℹ I expected the candle sticks to be drawn in the CombinedChartView.

What happened instead?

ℹ No candle sticks were drawn. The drawDataSetMethod incorrectly assumes that the chart is a CandleStickChartView, and in this case the chart is a CombinedChartView, so the drawDataSetMethod returns without drawing any candle sticks.
