[vtkusers] vtkQtChart - vtkQtLineChart and XY axis?

[shekharc]

Hi Paul,

I haven't tried a million points so I don't know. Performance that I do 
know is that it does do several 500+ double points plot (single plot 
multiple lines) instantly.

You can also use VTK in house plotter - vtkXYPlotActor class.

All the best.
Cheers
Shakes
