The plotting load mechanism should be constructed such that any 1-D rectilinear grid can be loaded and plotted.

I envision that objects producing these grids show up in the pipeline browser with everything else, except that their visibility toggle is available for plot type views. This fits well with the current implementation and future plans.

1D rectilinear grids can be loaded and plotted as described. I can "Save Data" from a histogram filter, then load it a show it in a bar chart view.

When I save the histogram data in any format and then reload it, the data looses its "preferred" view. That is, when I load the data back it places it right in a 3D view (where it shows nothing).

Is there some way we can preserve this information? It could be stored in the metadata for one or more file types. Should it be stored in pvd files (although not my format of choice for histogram data)? Should we have a new data format specifically for plots that captures the plot type information as well as the data? Should this be captured in a separate bug? Should we hold off on this until ParaView 3.2?

In the short term, when a 1D rectilinear grid is opened, if it has point data it will be defaulted to an x-y plot and if it has cell data it will be defaulted to a bar chart.

For ParaView 3.2, we should revisit a more robust mechanism for this. Perhaps a special format for plots.

This is working well on Mac and Linux, but I can't get it to work for my Windows build. Whenever I load a .vtr file I saved from a histogram, I get the following message in the Output window:

Failed to create a proxy for the requested view type.

I don't think this is a build dependency issue. I've recompiled from scratch.
