Java Shape Utilities

Question

How to set such kind of points - small circles? I know we should set render and ShapeUtilies:

render.setSeriesShape(NumberOfSerie, ShapeUtilities.[something here]);

what should i write to get this circles? Documentation is here.

Answer 1

The ShapeUtilities class has some methods to create shapes that aren't provided by default in Java2D. For circles though, you can just use:

Ellipse2D circle = new Ellipse2D.Double(-3.0, -3.0, 6.0, 6.0);

The circle here is centered on (0, 0) - JFreeChart relies on that because it will translate the position of the shape to (x, y) when drawing the chart.
