PointsColumn class
Represents a column of StackableValuePoints, with support for both stacked and non-stacked charts.
Corresponds to one column of data from ChartData.dataRows, ready for presentation by Presenters.
The
- unstacked (such as in the line chart), in which case it manages stackableValuePoints that have values from ChartData.dataRows.
- stacked (such as in the bar chart), in which case it manages stackableValuePoints that have values added up from ChartData.dataRows.
Negative and positive points must be stacked separately, to support correctly displayed stacked values above and below zero.
