Axis labels sometimes cropped (.pdf, Mtlab 2015a)

[hpay]

Either with or without the '-nocrop' option, my x axis labels are getting cut off on some plots.
baseW.pdf

Not sure why, they are perfectly visible on the figure window:

Otherwise, export_fig is perfect. Any ideas? This is my command:

export_fig(fullfile(cd,'results','baseW.pdf'),'-painters','-nocrop')

I have the same problem. As a temporary fix I suggest you "manually" adjust the axes size like this before exporting, in order to have more white space at the bottom:

ax.Position = ax.Position .* [1 1.5 1 0.9]; % <- where ax is the handle of the bottom axes

Adjust the proportions as you wish, it usually needs a few tries but after that it works.
