 [Matplotlib-users] Distance between axis and axis label From: Christian David Ott - 2005-11-16 09:57:46 ```Hi, I am a new user of matplotlib (0.82; python 2.3.5). So far I have used supermongo (sic!) to produce figures for physics journal articles and talks. I am trying to get up to speed with matplotlib to do the same kind of plots with an open source package. For talks I like to prepare eps figures which I embed in my latex-based slides. For slides, huge font sizes are a must, hence I like to use large fonts for tick mark labels and axis labels. My problem: For the axis labels, matplolib (or the PS backend?) is apparently not adjusting (or rather: under-adjusting) the distance between axis and axis label. Is there a way to adjust the distance between an axis and its label? If not, then where in the code is the distance calculated, scaled and set? I have dug through the code, but could not find it due to lack of object-oriented programming experience, I guess. Here is an example of what I mean. The x-axis labels comes out sort of okay, but the y-axis label is to close to the y axis. #!/usr/bin/python from pylab import * from matplotlib import rcParams plot([1,2,3,4], [1,4,9,16], 'ro') xlabel("something",size=3D30) ylabel("something else",size=3D30) xlabels =3D getp(gca(), 'xticklabels') setp(xlabels, size=3D25) ylabels =3D getp(gca(), 'yticklabels') setp(ylabels, size=3D25) savefig("testplot.eps") Note that playing around with 'axes' did not help - it has no influence on the distance between labels and axes. Help & comments much appreciated! Thanks! - Christian ```

But this merely changes the distance between ticks and tick labels. The distance between tick labels and axis label stays constant. To be more precise about what I need (my first e-mail was a bit ambigous...sorry): I need to change the distance between tick labels and the axis label. Thanks. - Christian ```

This could work great for scalable back-ends like EPS. If you need a PNG, you should be able to accomplish it by manipulating the size and the dpi settings. See: http://www.scipy.org/wikis/topical_software/AdjustingImageSize For more info about this. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@... ```
 Re: [Matplotlib-users] Distance between axis and axis label From: Ryan Krauss - 2005-11-16 17:31:43 ```I am confused as to what the problem is. Are you saying that your axis label is running into you tick label? Can you post a little piece of a png showing the problem you are trying to solve?

Anyway, the below code generates a plot that reproduces my problem. The y-axis label is to close to the y-axis tick labels (though not overlapping). I would like to shift the y-axis label further away from the y-axis tick labels. - Christian ------------- #!/usr/bin/python from pylab import * from matplotlib import rcParams plot([1,2,3,4], [1,4,9,16], 'ro') xlabel("something",size=3D30) ylabel("something else",size=3D30) xlabels =3D getp(gca(), 'xticklabels') setp(xlabels, size=3D25) ylabels =3D getp(gca(), 'yticklabels') setp(ylabels, size=3D25) savefig("testplot.eps") ```

It seems you need a pad setting for the distance from the axis label to the tick mark labels, but I don't see one in the rc file. Anyone else?

There is an Axis property LABELPAD that can be set -- it has not been exposed to rc yet but should be. Something like ax.yaxis.LABELPAD = 5 should work for now. Let us know .... JDH ```
