[vtkusers] Looking for an incrementable plot in VTK

[gdherbom]

Hello, 

I am looking for a VTK class to plot realtime 2D data with a frequency of
about 100Hz. Typically the graph is like an oscilloscope and I would like to
use it in a Qt application. 

I try vtkChartXY but the performances are not enough good when I zoom during
plotting. 

I try to code something but I am new with VTK and I have a lot of difficulty
to find functionnalities to manage automatically the scaling, zoom, panning,
etc. 

I attach my code to this post.

export_oscilloscope.tar.gz 

Thanks. 

Gerald
