A category area chart represents the items using polygons that fill the area between the domain axis and the data points. |
|
The area chart is based on Category Plot and Category Renderer. It inherits all their properties.
This is what category area chart looks like:
Category area chart supports two renderers.
Area Renderer
A renderer that draws different data series one over another. Since different series overlap each other, they are rendered semi-transparently. The transparency is controlled by Foreground Alpha property of the chart plot.
Stacked Renderer
A renderer that "stacks" different data series one over another.
Dataset
