StepAreaSeries<T, D> class

Renders the step area series.

A step area chart is a form of area chart which is useful for displaying changing numeric values over a period of time.

The x-axis in a step area chart represents a period of time, and values are plotted on the y-axis at constant or irregular time intervals.

Step area charts are similar to step line charts, except in a step area chart the area occupied by the data series is filled in with color.

To render a spline area chart, create an instance of StepAreaSeries, and add it to the series collection property of SfCartesianChart.

Provides options to customize the color, opacity, width of the StepArea segments.
