Is the QtChart considered mature? I mean, is there going to be any major changes to the way it draws, displays, and processed data?<br><br>Or is that part of it considered done?<br><br>From what you are saying, it sounds like the development will be focussed entirely on creating a bridge between vtk data and the chart. is that correct?<br>

The Qt chart library is being maintained by several people at Sandia<br>
National Labs, ETI, and Kitware. It is a very new feature (after VTK<br>
5.2). The code inside GUISupport/Qt/Chart is indeed VTK-independent,<br>
while the layer of VTK interoperability is located in GUISupport/Qt.<br>
There are classes there to adapt a vtkTable into a Qt item model to<br>
use in a chart, and also to treat a chart as a vtkView subclass (see<br>
VTK/Views for other view classes).<br>
<br>
I agree that TemperaturesBoxPlot needs to be removed or significantly cleaned.<br>
<br>
In the immediate future, the VTK interoperability layer will go<br>
through an overhaul to simplify the process of creating a chart from a<br>
VTK data object.<br>
