2014b axis label errors when printing to postscript
8 views (last 30 days)
I am getting spaces in the axis label when I use a subscript. This behavior is new with 2014b, the same function for sure doesn't do this is 2013a. I was having troubles using greek letters as well, but found a work around. The issue with the Greek letters went away when setting the axis label font weight to normal, setting it to bold caused the issue (directly or indirectly, not sure). Any thoughts on why the print command is behaving differently? Currently using painters rederer, which is needed for impage quality and file size. I am also using MATLAB on Linux.

This is under investigation by our developers.
We have found there is a gap, the size of which is dependent on the length of the first string, between strings in postscript and pdf output when painters is used. The problem does not occur when using opengl or printing to an image format or to a printer.
Invoke opengl when printing with -opengl flag.

The problem appears to be due to the way that bold characters are handled. A quick example using R2014b:
plot(0:0.01:2*pi,sin(0:0.01:2*pi)); xlabel('\eta'); print('-dpdf','test')
The above code creates the correct pdf using the default export settings. When the font is changed to bold however, the "eta" is printed as "2"
Changing to a raster image format (eg png) does export the text correctly, but I agree with Aaron. Raster graphics are not good enough for publication.

I've just committed a fix in export_fig for this Matlab bug - any Tex/LaTeX strings will now appear unbolded in the output, but at least they will be displayed correctly. So anyone who finds this bug annoying can either unbolden their labels, or use export_fig instead of print().
