Everytime I save figures of simple line plots using savefig() without any additional variables, it’s black instead of blue when I reopen the file. Any good reason why it is like that?

line(((1:length(stimsignal))/fs)*1000,stimsignal);

xlabel('Time (first 250 ms)');

ylabel('Signal amplitude (relative)');

title('Signal in the Time Domain');

savefig('figure1.fig')

Many thanks!

EDIT: it's the line() function that screws up the colors when you try to save them in a .fig; Use plot() instead and it's fine!

This is not the expected behavior. Can you write a small code sample of how you are creating, saving, and loading the file?

Loading file by double click.

Hi Florian,

I was not able to reproduce this error by generating the fig file based on the above code snippet and then opening it by double clicking. However, you may be able to resolve your issue by referring to the following MATLAB Answers post:

If this does not fix the issue, could you possibly provide the complete MATLAB script that you are using?
