How to get different color in legend, getting same dashed green color for I3,I2 , should be as plotted I3 green and I2 to be blue

disp(f2);

plot( L_interp, I3, 'g--' ,L_interp, I2, 'b--',L_interp, I4, 'r--',L_interp, I, 'k--');

xlabel('wavelength');

ylabel('I');

legend('I3', 'I2');

Thank you

Please share your whole code including any data you have. You can copy and paste it here directly or attach it using the paperclip button.

Your Code should work. I simplified it and ran it here (see below).

You can try the following:

clear  % run this
clear 'all'  % and also try this

% before you plot make a line like this (this forces a new figure)
figure(10); hold on; grid on; clf;

And also try restarting Matlab. If this also does not help you have to provide the whole code (as already suggested). Maybe you plot I3 before for some reason. This can be tested: Just enter more names in the legend:

legend('test1', 'test2', 'test3', 'test4', 'test5', 'test6', 'test7', 'test8')

The Code that works:

L_interp = linspace(0,10,10);
I3 = rand(1,10);
I2 = rand(1,10);

plot(L_interp, I3, 'g--', L_interp, I2, 'b--');
xlabel('wavelength');
ylabel('I');
legend('I3', 'I2');

thank you, it worked

i used hold on

plot( L_interp, I3, 'g--');

hold on

plot(L_interp, I2, 'b--');
