Change viewer setting in custom python reader

Good afternoon,

I wrote a Python plugin for Paraview using the routines in paraview.util.vtkAlgorithm. It works great, but I want to change some of the viewer settings when the file is opened (pick which scalar use for color, change from “Surface” to “Surface with Edges” … that sort of thing).

That kind of code doesn’t seem to fit in RequestInformation or RequestData. Is there a logical place for those settings?
