Overview

IGStepAreaSeries displays a polygon, the outline of which is a set of connected parallel vertical lines that pass through each of the series data points and the X axis. This series has string labels along the X axis and numeric values along the Y axis. This series uses IGCategoryXAxis or IGCategoryDateTimeXAxis and IGNumericYAxis. The data source for this series is a collection of single value, single label points. IGCategorySeriesDataSourceHelper can be used as the data source for IGStepAreaSeries.

Multiple series of the IGStepAreaSeries type are handled the same, regardless whether or not they share the same X axis. The series with the higher index will be drawn in front of the previous series.

Markers, when enabled, are placed at the locations of data points.
