New issue 1307: Add capability to visualize a single variable on multiple meshes https://bitbucket.org/yt_analysis/yt/issues/1307/add-capability-to-visualize... Alexander Lindsay: - Starting with SlicePlot initially, it would be great to be able to visualize a variable that exists on multiple (most often geometrically and physically connected) mesh blocks. - This is probably unique to UnstructuredMesh (at least for now) Currently have a hacky solution...will refine over the next couple days.
