issue with MATLAB figure

I create a figure xx.fig, now I save it as: xx.jpg. Eveything is fine. Now I made a copy of this file yy.fig because I need to modify the font size to have better resolution. Only I increased the font from 220 to 22. When I save the file as jpg, it gives me bad resolution compared with the previous one. What is the reason? I can not modify the font.

Thanks inadvance for your quick response.

Hi Aymen Zreikat,

Please have a look at the export function you use. I recommend to use print() since it comes with several configuration options.

close all

data = rand(1,100);
data = [1:100; data];

fh = figure;
ah = axes(fh);

plot(ah,data(1,:),data(2,:))
ah.XLabel.String = 'Cell Radius (km)';
ah.YLabel.String = 'Max Nr. of User (-)';

ah.XLabel.FontSize = 22;
ah.YLabel.FontSize = 22;

print(fh,'TestFigure','-djpeg','-r0')

Kind regards,

Robert

Robert,

This is the reason for getting different resolutions? but it works in the first time, why when you need to change the font from the "figure editor", it gives you low resoltion?

This means I have to use your method only?

Thanks

Hi Aymen Zreikat,

storing jpg-files from figure editor changes resolution to standard value. According to documentation saveas() standard resolution is 150 dpi which is quite low for publication ready illustrations. The method I introduced to you, allows you to save your figures in actual screen resolution which is triggered by the "-r0" command.

If you want to save your figure in any defined resolution I recommend my answer here: https://de.mathworks.com/matlabcentral/answers/415952-plot-resolution-and-size?s_tid=srchtitle

Saving high-res pixel graphics is only possible using command line according to my knowledge.

Thanks a lot
