[vtkusers] vtkChart

[Eric E. Monson]

(Marcus, there's a note for you towards the end.)

Just as a point of interest: After playing around a bit myself, since I don't use C++ VTK on Windows very often, it turns out that I have runtime (not build) problems with that specific LinePlot example. (Any build errors I got along the way were related to mismatched Release/Debug/etc versions between how I set up my VTK build and my example program build – decided to go with all Release for my testing.)

Running that LinePlot example just showed me a black window with no chart in it. It works fine, though, if I follow something like the Bar Chart example and change

  vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
  renderWindowInteractor->SetRenderWindow(view->GetRenderWindow());
  renderWindowInteractor->Initialize();
  renderWindowInteractor->Start();

to 

  view->GetInteractor()->Initialize();
  view->GetInteractor()->Start();

This is with VTK git version from yesterday on Window 7 64-bit built in Release mode using Visual Studio 2010 x64 compiler option. (CMake 2.8.4 to create the VS solution.)

I think I'm going to just edit the example to lock in that change, since the first way is pretty non-standard.

Marcus, I also get some axis numbering rendering problems off and on. I'll attach an example. It persists on zooming the axis, although sometimes when the particular number that's being affected leaves the view and then comes back it's okay for a while...
