[vtk-developers] Extension to vtkParallelCoordinatesActor

[David Cole]

Submit it as a "feature request" to the VTK bug tracker. ( at
http://www.vtk.org/Bug ) Then, once you've added an entry there, you can
attach your patch to the bug tracker entry.

Others can download it from there, try it out, give you feednack and even
vote for the bug tracker entry if they think it's worthwhile.

HTH,
