Demonstrates how to use Stacked Column API in SciChart Android.
When you add multiple StackedColumnRenderableSeries into VerticallyStackedColumnsCollection for vertical grouping or into HorizontallyStackedColumnsCollection for horizontal grouping  it allows to render them stacked one above another or side by side. Data provided by its DataSeries can be used to render an XyDataSeries (which contains one X-point and one Y-point), XyyDataSeries (renders Y values), XyzDataSeries, HlDataSeries and OhlcDataSeries(renders Close values). Columns are drawn using the pens provided by the setStrokeStyle(PenStyle) (outline) and using the Brush provided by the setFillBrushStyle(BrushStyle) (fill).

Tip!

Do you need to change the width of a column? Try calling the setDataPointWidth() method passing in any number from 0.0 to 1.0. This alters how much space a column takes up.
