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

Solution

  • 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.
