New data in same plot

Hello everyone,

I'm trying to keep the plot of a variable in the same figure in which the data of the new data for this variable gets plottet when I run the code again, so I see the changes in the plot that result after changing of certain parameters.

Can somebody help me with this?

Thanks in advance!

In some cases you can use hold

This will, however, not work if the code contains a call to figure that does not have a numeric parameter , such as if it calls

figure()

That call would open a new figure and further drawing would typically happen on the new figure.

If understood your question correctly, simply use hold command, e.g.:

t = linspace(0, 2*pi, 1e3);
L = {};
for omega = 1:5
    F = sin(omega*t);
    plot(t,F), hold on
    L{omega} = ['\omega = ' num2str(omega)];
    legend(L{:})
end
