JFreeChart - how to reverse axis order

Question

I\'m creating XYPlot and I need to reverse the order on y-Axis (that is, I need lower numbers to be higher on the axis). I would appreciate any hints how to do that.

Answer 1

I had the same problem as you. I found this:

ChartPanel.getChart().getXYPlot().getRangeAxis().setInverted(boolean)

Answer 2

to reverse the Y-axis ... you can use

ChartPanel.getChart().getXYPlot().getDomainAxis().setInverted(boolean)
