Hei Eric,
i will have a look on that SIGLE plugin too.. should be somewhere on my
desktop. Actually the problem with JFreeChart is that one needs a doc.
@Sunburned: I did not use a JDialog yet - only a frame. But I am going
to try the dialog next.*)
I also recognized, that the screen-errors appear if I put OpenJUMP in
background, i.e. Eclipse on top, and then again on top. The histo-plot
is fine, but not OJ.
stefan
*) I tried.. and it does not work as well whith a Dialog. Seems like
there is no other way then looking in the sourcecode of jmathplot.
