Dear all, The newest version of the matplotlib easybuild sets the MPLBACKEND environment variable to Agg. This causes our users to complain that they can no longer plot interactively.
I seem to remember that this was done because not setting it caused test scripts to try to open X11 windows, which is clearly not a good thing. But would it not be a better solution to have the test scripts set the backend they expect? In particular since setting MPLBACKEND can be done before the module is loaded, but unsetting can only be done after it is loaded, so all scripts importing the module will have to be modified. Setting MPLBACKEND in interactive scripts may not be a good idea, since on Linux you want TkAgg but on macOS you want MacOSX.
