[vtkusers] Please help! Problem with vtkXYPlotActor

[piantado at email.unc.edu]

Hi, I'm trying to use vtkXYPlotActor in java to draw graphs. I'd like 
for the user to be able to change the x range on them but calling 
SetXRange(-range, range) doesn't work for all values. For example, it 
works fine when range=10, but when range=30 the graph's range becomes -
50 to 30, instead of -30 to 30. Calling GetXAxisActor2d().SetRange(-
range,range) will keep the data in the range but does not change the X 
axis. Does anyone know what I'm doing wrong?
Thanks,
++Steve
