Talk:Plotting Parallel Data (PGraph)

Is Array Representation Sufficient?

The entire approach depends on representing plot data as 1D or 2D arrays? Will this always be the case? Are there use cases otherwise?

Non Qt plotting components?

Is it too restrictive to say that the plotting components will be in Qt? There may be some cases to use VTK to generate some of the plots.

For example, the easiest way to implement an X-Y-Z plot is with a 3D drawing package like OpenGL. And if we are using OpenGL anyway, why not let VTK do the work? This is how Prism does its X-Y-Z plots.

Also, it may be handy to have both Qt component plotting and VTK plotting for other types. That would make it possible to do plotting on a tiled display. I know, people say plotting on a tiled display is pointless, but what about putting up lots of plots for comparitive vis? What about really detailed scatter plot for a large amount of data?

There may even be cause to have a "plotting component" that is neither Qt nor VTK/OpenGL. What about a component that outputed an image file such as an encapsulated postscript, pdf, or image? What about a component that outputed a data file to be imported in another package such as excel or grace?

Ultimatly, I think there are two questions. First, should references to "Qt Plotting Components" be changed to the more generic "Plotting Components"? Second, should there be some consideration for plots that happen on the server side?
