<div><br>

<div>BUT --- If I do,</div>
<div>export DYLD_FALLBACK_LIBRARY_PATH=/Applications/paraview4.3.1.app/Contents/Libraries/<br>
</div>
<div><br>
</div>
<div>and then start Paraview from the command line,</div>
<div><br>
</div>
<div>/Applications/paraview4.3.1.app/Contents/MacOS/paraview<br>
</div>
<div><br>
</div>
<div>... and load the state file and the bluntfin.vts file ... Now I can see the matplotlib plots!!!!!!</div>
<div><br>
</div>
<div>So it looks to me like you aren't setting a dynamic library path correctly within Paraview's python. </div>
<div><br>
</div>
<div>Hope this helps. Thanks for the simple thing to try. </div>

<div>I am running the exact same version of ParaView (my About box has the same contents as yours), so this is a little bit puzzling.</div>

</div>
<div>Could you try two things:</div>
<div><br>
</div>
<div>1). Run ParaView, create a Python View, then enter this script:</div>

<p style="margin:0px">print matplotlib.backends.__file__</p>

</p>
<p style="margin:0px">Please report what the Output Messages window says.</p>
<p style="margin:0px"><br>
</p>
<p style="margin:0px">2). Open the contents of your ParaView Mac bundle (right-click, "Show Package Contents"), open up Contents -> Python -> matplotlib -> backends. Please let me know if you see a backend_agg.py file in there.</p>

<div dir="ltr">Hi Cory and Utkarsh - So I never see a plot - just a black window. The error message I sent earlier repeats every time I move my mouse over the python view window. I'm using Paraview 4.3.1 downloaded from
<a href="http://paraview.org" target="_blank">paraview.org</a>. Paraview's "about" box is below.

</div>
<div>I am trying to reproduce this with ParaView 4.3.1 64-bit on a Mac with Yosemite 10.10.2, but haven't been able to. This is the latest Mac binary available for download on
<a href="http://paraview.org" target="_blank">paraview.org</a>. The matplotlib pot shows up as in the blog post. Is your ParaView binary from
<a href="http://paraview.org" target="_blank">paraview.org</a>?</div>
