[vtkusers] vtkQtChart ?

[Jeff Baumes]

The Qt chart library is being maintained by several people at Sandia
National Labs, ETI, and Kitware. It is a very new feature (after VTK
5.2). The code inside GUISupport/Qt/Chart is indeed VTK-independent,
while the layer of VTK interoperability is located in GUISupport/Qt.
There are classes there to adapt a vtkTable into a Qt item model to
use in a chart, and also to treat a chart as a vtkView subclass (see
VTK/Views for other view classes).

I agree that TemperaturesBoxPlot needs to be removed or significantly cleaned.

In the immediate future, the VTK interoperability layer will go
through an overhaul to simplify the process of creating a chart from a
VTK data object.
