I have looked into the a few example sand tried using several of them as a starting point but seems like with each one I run into a problem I can not figure out.<br>

<br>/vtkExtractHistogram2D looks easy and promising but lacks any kind of example of how to correctly connect it with a actor, mapper, and renderer so I am not sure how to use that...<br><br><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/HistogramXYPlot" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/HistogramXYPlot</a>: I can not figure out how to read in my arrays into the histogram.<br>
<br>Can anyone help me figure this out?<br><br>Luke H<br>
