[vtkusers] Problems with vtkXYPlotActor

[schluperman]

Hi,
has anybody tried the Example Annotation/xyplot.tcl?
I tried to use it with c++ but i always get the error Message at the 
probe Filter line.
Because p13d is vtkStructuredGrid and must be 
vtkdataset('vtkProbeFilter::SetSource' : cannot convert parameter 1 from 
'vtkStructuredGrid *' to 'vtkDataSet *'). Am I doing anything wrong or 
is the Example wrong?

Thanks Christoph
