New issue 1145: ParticlePlot docs have several empty images being rendered https://bitbucket.org/yt_analysis/yt/issues/1145/particleplot-docs-have-seve... Cameron Hummels: The [ParticlePlot docs](http://yt-project.org/docs/dev/visualizing/plots.html#particle-plots) have several images that are clearly not plotting what they are supposed to be plotting, so it looks like some of the infrastructure got changed and broke something. Notably, the [last stable version of the docs](http://yt-project.org/docs/3.2/visualizing/plots.html#particle-plots), version 3.2, does not suffer from these problems.
