jfreechart - Java Shape Utilities -

how set such kind of points - small circles? know should set render , shapeutilies:

render.setseriesshape(numberofserie, shapeutilities.[something here]);

what should write circles? documentation here.

enter image description here

the shapeutilities class has methods create shapes aren't provided default in java2d. circles though, can use:

ellipse2d circle = new ellipse2d.double(-3.0, -3.0, 6.0, 6.0);

the circle here centered on (0, 0) - jfreechart relies on because translate position of shape (x, y) when drawing chart.
