Hi all, I'm writing regarding an issue I'm having porting the yt package to properly handle some of the changes in matplotlib 1.4.
yt is a python library for analysis and visualization of volumetric data, with a focus on astrophysical simulation datasets. We use matplotlib heavily for visualization tasks. For a while now, we've been using the natural neighbor interpolation in matplotlib.delaunay to generate contour plots from image data. See for example, this function: https://bitbucket.org/yt_analysis/yt/src/84b551a47ac462d646963f0b13e4dd0e85bd9751/yt/visualization/plot_modifications.py?at=yt#cl-311 In this example, self.triang is an instance of matplotlib.delaunay.triangulate.Triangulation. The bug report I opened regarding this issue might also be informative: https://bitbucket.org/yt_analysis/yt/issue/764/matplotlibdelaunay-deprecated-in I'm writing because it seems that matplotlib.delaunay was deprecated recently. This means users who import the yt plotting code will see a DeprecationWarning if they are running the upcoming matplotlib 1.4 release -- definitely an undesirable situation. Unfortunately, it looks like the workaround for this issue is to use natgrid to generate the interpolation. This is undesirable from our point of view since we have no way in general to control how users build their matplotlib installation. I'm curious whether any of the matplotlib developers have alternate ideas for how to do deal with this.
