JFreechart, Line Chart with filled Areas

Question

I am trying to create chart like below:

While I've almost achieved everything by simply creating a line chart and customizing shape/paint for Renderer, I can't seem to find a way to fill the areas under the series line.

Any clues, how can I do this?

Answer 1

You could create your chart with a StackedXYAreaRenderer. Specify AREA_AND_SHAPES in the constructor and enable outlines. See the ChartFactory code for createStackedXYAreaChart() as an example.

StackedXYAreaRenderer r = new StackedXYAreaRenderer(XYAreaRenderer.AREA_AND_SHAPES);
r.setOutline(true);

Given a renderer, you can set the outline paint and stroke as desired.
