I'm exporting a figure of a plot using the exportgraphics function. For both vector .pdf and raster .png files, the sans serif LaTeX font is not shown correctly in both cases.

Snippet:

exportgraphics(fig, ...
    'output.png', ...
    'Resolution', 300) 
exportgraphics(fig, ...
    'output.pdf', ...
    'ContentType', 'vector')

Where 'fig' is the figure object in question. Also, MATLAB shows the following warning:

% Error updating Text.
% Font cmss10 is not supported.

Below is a comparison of what I see in MATLAB and what the exported .png looks like.

MATLAB:

PNG output:

The vector output in PDF looks just like the PNG.

Hi Johann,

I understand that facing some problem while exporting the plotted graph with Sans Serif Latex font.

To achieve this, please refer to the following code as example:

fig = figure;

plot(magic(5));

xlabel("testing (X)", "FontName","SansSerif", "Interpreter","latex")

ylabel("testing (Y)", "FontName","SansSerif", "Interpreter","latex")

ax = gca;

exportgraphics(ax, 'output.png','Resolution', 300)

exportgraphics(ax,'output.pdf', 'ContentType', 'vector')

By following these steps, you should be able to export a figure with labels in sans serif LaTeX font in both JPG and PDF formats using “exportgraphics” function in MATLAB.

You can refer to these MATLAB documentations for more information:

I hope this helps.

Thanks for your help, Avni.

Unfortunately, if you look closely in the image you uploaded yourself, you will notice that the font family of the labels is LaTeX's Serif font, and not the Sans Serif one. That is even stranger since the ticks are the correct Sans Serif font. I tested your code and got the same result.
