y-axis label no longer obeys x position in 2.0

Using matplotlib with Seaborn's FacetGrid. Before upgrade to 2.0, setting the x,y position of the y-axis label worked. Now only y-position is respected.

import seaborn as sns
import matplotlib.pyplot as plt

g = (sns.FacetGrid(df, col="prenom", hue="sexe", col_wrap=3, size=3, sharey=False, legend_out=True)
 .map(plt.plot, "annee", "freq", ms=3, linewidth=3))

g.set(xlim=(1980, 2015), xticks=[1980, 1990, 2000, 2010], ylim=0)
g.set_titles('{col_name}')
g.fig.subplots_adjust(top = 0.91, wspace=0.3, hspace=0.3)
g.set_titles('{col_name}', size=13, fontweight='bold', ha='left')
g.set_axis_labels('', 'BABIES')

### This is the line that is not working ###
g.set_ylabels(rotation=0, position=(0, 1.04), color='grey')

g.fig.suptitle('Names that changed gender', x = 0.1, ha='left')
sns.plt.legend(loc='upper left',bbox_to_anchor=(1.5,1))
sns.despine()

It doesn't mater if I put 0 or 999999999 as the x value in the position parameter. The label is always in the same horizontal place.

Matplotlib version 2.0, Python 3.5 on Mac OSX El Capitan in Jupyter notebook
Matplotlib installed via conda update matplotlib

It would be useful to have an example that does not rely upon seaborn in order to isolate the source of the bug. The bug could very well be in seaborn's FacetGrid, for all we know...

You're right, my apologies. Here's an example in pure matplotlib. The x position is still ignored.

roberto = noms[noms.prenom == 'roberto'.upper()]
roberto = roberto.pivot_table('freq', index='annee', columns='sexe')

fig, ax = plt.subplots()
ax.title.set_text('Babies named Roberto')
ax.plot(roberto)
ax.axes.set_ylabel('BABIES', rotation=0, position=(2000,1.05))

Here is the full code to reproduce the problem:

import matplotlib.pyplot as plt
import numpy as np

roberto = np.random.randint(0, 100, size=(10, ))

fig, ax = plt.subplots()
ax.title.set_text('Babies named Roberto')
ax.plot(roberto)
ax.set_ylabel('BABIES', rotation=0, position=(2000,1.05))

I have the same results on matplotlib 1.5 and matplotlib 2.0.
Which version of matplotlib are you using?

I just upgraded to 2.0 via conda.

After a play around I've found that by setting position=(x,y), y is in figure co-ordinates, so y=0.5 puts the label halfway up the axis. Setting x=2000 (if it worked) would probably put the legend way off the the right of the figure.

I can't seem to be getting it working in 1.5.3 either, do you know what version you upgraded from?

Oh, I put 2000 in there just to show that no matter what x value I set, it didn't make a difference. I should have been clearer. I'm sorry, I don't know what version I upgraded from.

Hmm, I'm not convinced setting x location of a y-label or y location of an x-label ever worked. The relevant line which sets the label location I think is https://github.com/matplotlib/matplotlib/blame/master/lib/matplotlib/axis.py#L2161 which hasn't changed for at least 5 years.

It might be worth another dev having a look... In the meantime I'd recommend just adding a normal text box to the plot which should give you full control over position.

Punting this to 2.1 as no-one has disagreed (yet) with my assertion that this never worked.

After a bit of a hunt, I think this is a duplicate of #7112

I understand, thanks for the explanation.

Well, it's because tick labels have different width, e.g. the label for the value -1 is very large compared to, say, the labels for 1,2,3, etc. In my case I only have one label with the minus sign which is pretty far from the axis label. So it is OK to have the label nominally overlapping the tick labels, since in practice it does not (they are physically far apart). Actually, it looks better to have it closer to the axis.

For what concerns me, now I have understood how this works, and that is fine.
However, maybe it is good to get rid of some inconsistencies on the long run.

So for example, compare:

ax = plt.gca()
ax.xaxis.set_label_text('x-label')
ax.xaxis.set_label_coords(0.5,0.5)

with

ax = plt.gca()
ax.set_xlabel('x-label',position=(0.5,0.5))

It seems reasonable that the two snippets should do the same, but they do not.

Sure, I agree - thats the suggested fix, is for someone to make the automatic label repositioning over-rideable with manual values if desired, like we did in #17127 for the title.

This issue has been marked "inactive" because it has been 365 days since the last comment. If this issue is still present in recent Matplotlib releases, or the feature request is still wanted, please leave a comment and this label will be removed. If there are no updates in another 30 days, this issue will be automatically closed, but you are free to re-open or create a new issue if needed. We value issue reports, and this procedure is meant to help us resurface and prioritize issues that have not been addressed yet, not make them disappear. Thanks for your help!
