I\'m using the still undocumented HG2-Update to create my MATLAB plots, because they just look that much nicer.
I had the same problem and used the workaround from thewaywewalk. Now I discovered the MATLAB function "hgexport" works under HG2 (in R2014a).
An issue still was the paper size. I want to use the same size for all graphs with as little white frame as possible. Here you have to set two sizes:
The papersize is set with set(gcf,'PaperSize',[width height]) and the size of your chart is set through export styles. These are set in "Export Setup" or command line:
exp_style=hgexport('readstyle','default');
exp_style.Width = 'width';
exp_style.Height = 'height';
exp_style.Renderer = 'painters';
Now you can export your pdf:
hgexport(gcf,'pdfname',exp_style,'Format','pdf');
PS: In HG2 you may also use Latex for tick labels:
set(gca,'TickLabelInterpreter','latex');
Exporting vector graphics using the yet not official HG2-Update is quite an issue. The .pdf-export is still totally screwed up. What is working fine is the .svg-export, apart from that the boundary box is not set properly.
The long workaround would be:
Save the plot with '-dsvg' (print-command) or 'svg' (saveas-command) as vector graphic, open the file in the open source application Inkscape and save again as .pdf with the Export area is drawing checkmark set.
Quite complicated, so I found a way to do it via command-line directly from Matlab (Inkscape still required!):
filename = 'test';
inkscapepath = '"C:\Program Files (x86)\Inkscape\inkscape.exe"';
%// save as .svg
saveas(gcf,filename,'svg')
%// open and save with "export-area-drawing" set via command line
system( [inkscapepath ' ' filename ...
'.svg --export-area-drawing --export-pdf=' filename '.pdf'])
It takes some time, but works without any known issues for now.
Additionally delete the svg-File afterwards:
delete([filename '.svg'])
