Generates an iOS Stacked Bars chart. A Stacked Bars chart is a Stacked Column chart rotated 90 degrees, so that the columns are rendered horizontally. In order to achieve this effect, we create a Stacked Column chart, then use the XAxis and YAxis alignment to rotate the chart. See Documentation on how to use this type here: The iOS Stacked Column Chart.

The SCIStackedColumnRenderableSeries API can be used to render columns stacked above each other, or side by side in either Swift or Objective C. Grouping is performed when you place multiple SCIStackedColumnRenderableSeries into a SCIVerticallyStackedMountainsCollection or for horizontal column groups, the SCIHorizontallyStackedColumnsCollection.

Data is provided by a DataSeries, e.g. the SCIXyDataSeries, XyyDataSeries (uses Y1 only) or SCIOhlcDataSeries (renders close).
