[vtkusers] Questions about vtkXYPlotActor

[Gopalakrishnan, Gowri]

I think you do not need to create a different plot actor for every data set.
Here is the part of the example from vtk user guide

Vtkxyplotactor *xyplot
Xyplot->AddInput(probe->GetOutput());
Xyplot->AddInput(probe2->GetOutput());
Xyplot->AddInput(probe3->GetOutput()); etc....

Try this and if you still have problem I can run a test here.

Subject: [vtkusers] Questions about vtkXYPlotActor

Hi all,

I try to use vtkXYPlotActor for showing two or more plots of some data 
in different colors. For one plot everything works fine, of course. For 
showing two or more plots I create new vtkXYPlotActors for every 
dataset. I can see the different plots in the render window but it 
seems that every dataset draws its own x- and y-axis with its own 
scala. What is the best way to solve the problem? Is it possible to use 
only one actor? Is there a way to compute a unique scale for all plots?

thanks for your help
