New issue 660: Support for interactive MPL backends https://bitbucket.org/yt_analysis/yt/issue/660/support-for-interactive-mpl-b... Sam Skillman: We should have better support for operations such as SlicePlot.show() to display in an interactive backend, much like what the PlotCollectionInteractive had. This will need to be done by detecting the backend, determining if it has interactive capability, and reporting useful error messages if not. If "sl" is a SlicePlot instance, the following would be nice to have: ``` #!python sl.show() # Pops up a window for each field. sl.[set_zlim, set_width, set...] # Modifies the existing window(s)/creates new one(s). ```
