style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I am using two vtkLineWidgets with
two vtkXYPlotActors and a vtkImageActor in the same render window but with
their own renders. I’m displaying a 2D representation of a 3D object
containing points and scalars, and using the LineWidgets->GetPolyData() to
get cross sections to display in the XYPlots. The problem I’m having is
that I’d like one of the XYPlotActors to be displayed in a vertical
orientation. I’ve tried the ExchangeAxes() method, but this only swaps
the axes, not the data. I’ve also tried rotating the camera associated
with one of the XYPlots, but no luck. <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I have a couple further ideas, but
thought I’d look for some advice. My other ideas are: to extract the X
and Y arrays from the LineWidgets->GetPolyData() and then swap them; or to
use separate render windows for each plot and the 3D data. I’m not quite
sure how to extract the XY arrays from the PolyData for the first idea, and
the second idea seems messy. Anyone have any other ideas?
Thanks,<o:p></o:p></SPAN></FONT></P>
