I try to use the AvantGarde font in a MATLAB figure plot. However on the figure, the font is not displayed. I have the R2015a MATLAB version on Ubuntu.
When I use the *listfonts command, the AvantGarde font is listed as available.
When using uisetfont, the AvantGarde font is working and display without any problems. As shown here (uisetfont command):

fontname = 'AvantGarde';
set(0,'DefaultAxesFontName',fontname,'DefaultTextFontName',fontname);
Here an extraction of my output where the problems occurs:
I don't understand where the problem comes from and why the choosen font is not used for my figure, any help would be appreciate
