Setting the default font for data tips in MATLAB
For quite some time I thought that it was impossible to change the font size of the data tips you can add to plots in MATLAB. This was very frustrating because I would use these figures in reports and the font on the data tip would be almost illegible. So I started digging deeper on Google and experimenting, trying to find a way to increase this font. Finally I figured out a way:
In your startup.m file, which is normally within the MATLAB folder that is located in My Documents or somewhere similar, you can add the following two lines to the bottom of the file:
set(0,’DefaultTextFontName’,’Arial’) % Sets Font Style
set(0,’DefaultTextFontSize’,12) % Sets Font Size
Now, when you generate a new figure in MATLAB (any open figures before you made this change will need to be regenerated), and place a datatip, it will generate the corresponding x and y axis information in nice big font.
Tried that, doesn’t really work. what am I missing?
Hi Aparna,
You tried creating a startup.m file and adding those commands? If that doesn’t work, perhaps in your plotting script/function, after you employ the plot command, try the following:
set(gca,’FontSize’,18)
Or whatever fontsize you want.
