Hey Antoine,
I'm not sure what changed in the mean time, but the problem is that the
instances of `az_imshow` aren't saved to anything (e.g. you should write
`implot2 = az_imshow(data, aspect='auto')`). I *think* what happens is that
you don't have any references to the object so it gets garbage-collected
and the events you create disappear. That's my made-up explanation.
