Tick labels not being factored when plotting a subsample of parameters

[Chris-Pedersen]

Hi!

I'm hitting an unfortunate tick label issue in that a parameter with a very small numerical value isn't having the tick labels factored out when plotting a small subsample of parameters. In the first case it works fine:

However whenever I try and only plot a subset of parameters, the ticks for the parameter A_s are no longer being factored.

I've tried playing around with the configure options, different max_ticks and font sizes, figure sizes etc, but none of this jigs the ticks into factoring. I also can't find a kwarg to pass anywhere. Do you have any suggestions? NB in the first case I'm still plotting a subsample of the parameters - there are 8 in the chain. It's only when I'm down to plotting 2 that this issue pops up.

Thanks very much!

Hey Chris! How odd, this isnt intended behaviour. Are you able to share the code snippet you used (and that data as well if possible) so that I can exactly reproduce (and fix) the issue?

[Chris-Pedersen]

Hi Sam, sure I'll upload a reproducible example tomorrow, thanks a lot for looking at this!

I've uploaded a zip file with a small subsample of the data and a notebook that creates two plots - one with the issue and one without. Thanks!

What a weird issue! So it turns out that the current version of matplotlib should only have a single formatter per axis (matplotlib/matplotlib#15376) and the PR to support multiple axes hasnt been merged (matplotlib/matplotlib#13482). Fixing the issue by creating new x and y formatters for ever axis, and the fix should be in v0.32.0 (which should be on pip by the end of the day)

v0.32.0 is now live, please let me know if this doesn't fix the issue for you :)

Working for me, thanks a lot!
