[visit-developers] Question on plots

I have a basic question on plots.
I'm trying to optimize the performance of the poincare plot by doing the
minimal set of filter updates. There are two things that can change:
1- The streamlines
2- Analysis parameters of the streamlines
There are two filters, streamline and poincare. I only want to execute
the minimal set.
A few questions:
I have added the attribute method: ChangesRequireRecalculation(). This
returns true if either the streamline or the analysis needs to be
However, if I return true, it seems to delete the plot's filters and re
executes the entire plot. And so I lose my cached streamlines.
If I return false, SetAtts() is called but no filters get executed.
Am I going about this the right way?
Is there another plot that is similar that I can follow?
