ATLAS style axis labels incorrect about mplhep HOT 10 CLOSED

Welcome @Popinaodude could you make a PR with the style changes? @kratsg does this look ok to you since it's your work originally?

The legend position is mpl related issue. We fixed it in next release. mplhep has a helper function for it for now mplhep.r_align()

from mplhep.

labelsizes are 30 by default in ATLAS (I did the conversion from the ATLAS style guide to the matplotlib). For reference

ATLAS dictates:

• Rectangular plot: 800x600 px
• Square plot: 600x600 px

Since the smallest dimension is 600px for plots, and the font default is 42 (font choice=4, precision=2), this means that the text size in ATLAS (set to 0.05) will be a fraction of the pad size: 600*0.05 = 30.

Perhaps it's a problem on my end, but here's the output for the same histogram at label and pad size 30 and 20 respectively:

@andrzejnovak is the specification in mplhep meant to be in points or pixels? If we follow atlas style, then it should be 23/24pt, or 30 pixels.

from mplhep.

@kratsg it should be in points. The labels do look a tad large to me, but if the current numbers are what the style guide dictates we should keep it.

@Popinaodude you've found the correct way to overwrite the default settings. If you have mpl 3.3+ there are two new rcParams

#xaxis.labellocation: center  # alignment of the xaxis label: {left, right, center}
#yaxis.labellocation: center  # alignment of the yaxis label: {bottom, top, center}

We should probably add these to the mplhep styles I think both ATLAS and CMS use the "right" aligned label position. Unsure about LHCb

the style guide dictates 30 pixels.

Ok, it should be scaled down then.

@kratsg I can make a PR, does this affect other font size settings?

Maybe. I assumed everything was pixels, but I guess mpl uses points by default which I didn't realize.

From a cursory look, these should get changed if they were in px, to pts and get the following proportions
