hi,
in my program, several different datasets are displayed in one chartpanel with a range axis for each dataset. when i have two different datasets (or even more) it always paints the first line red, the second blue, etc, so i have two or more red lines.
so what can i do to make sure that one specific color is only shown one time in one chart? i know i can change colors with setSeriesPaint, but i need to do that dynamically, because the number of datasets varies with every file i load into my program.
what would be the best way to solve this problem?
and additionally, is it possible to color the range axis the same color as the color of the according line?
different line colors

The plot should allocate unique colors to all the series by default. Can you post a small demo program that reproduces this problem?
There are three methods for changing the color of an axis:
setAxisLinePaint(Paint);
setLabelPaint(Paint);
setTickLabelPaint(Paint);
...but there is no mechanism to link these to the color of a series that is plotted against the axis, so you'll need to set the colors in your own code.

Read my blog Support JFree via the Github sponsorship programi found the same problem in another topic:
http://www.jfree.org/phpBB2/viewtopic.p ... eriespaint
my picture looks the same. here is my sample code:
about the colors for multiple axes. remember the MultipleAxisDemo1 in the JfreeChart Demo Collection? That is what I want 
I will try the three methods you suggested. Thank you.
