How can JFreeChart print a scatter point directly on the x axis?

问题

I try to make a scatter chart but the data point is not exactly at the (2,0) coordinate and only partly visible. The image shows the generated output from JFreeChart:

But it should be like this (made with GIMP):

Does anybody know how to do it?

thanks for any help!!!

For anybody else, here is the solution, which didn't satisfy me completely but is acceptable:

The interesting lines of code to do so were:

plot.setAxisOffset(new RectangleInsets(0, 0, 0, 0));
plot.getRangeAxis().setLowerMargin(0);
