I'm using matlab R2014b from within a slurm job (with the -nodesktop option).

If I leave the default size and position for the figure and axis, the figure comes out fine, but if I set larger values for the figure position and axis then the figure will be cropped when created from within a slurm job (with -nodesktop), as in the attached.

The problem can be reproduced with this simple code:

    mystyle = hgexport('factorystyle');
    mystyle.Units='normalized'; % if I leave this to the default (inches) it does't make a difference
    mystyle.FontMode='none';
    mystyle.Resolution = 100;
    fh=figure()
    plot([0 1],[0 1]);
    set(gcf,'Position',[1          25        1280         669]);
    set(gcf,'PaperPosition',[-2.4167    2.0156   13.3333    6.9688]);
    set(gca,'Position',[0.1300    0.1135    0.7750    0.8115]);
    figure_name='min_example_settingPos';
    hgexport(fh,[figure_name '.png'],mystyle,'Format','png');  
    fh=figure()
    plot([0 1],[0 1]);
    figure_name='min_example';
    hgexport(fh,[figure_name '.png'],mystyle,'Format','png');

I tried to use export_fig instead of hgexport, but the problem persists.

As an update, I think that this problem is likely to be related to a known failure of matlab to take into account resolution settings when exporting to png and other formats while running with the -nodesktop option:

I would like to add that the same problem happens when exporting to eps using export_fig. Since export_fig is the only tool that correctly exports figures to eps in matlab as far as I know (hgexport, print or saveas would not respect custom-set horizontal and vertical resolution even with the normal GUI running), this leaves me with little hopes of being able to generate figures with the desired resolution from within a -nodesktop job. Any help would be greatly appreciated.
