Hello all, my .m file includes multiple plots. When I run the code only the last plot figure shows up and overwrites all previous plots. Any suggestion on how to manage this ?

Many thanks

How do you initate a figure? Some code would be useful here.

Your first plot command opens a figure and all following plot commands update that figure. To open new figure windows, use

figure()

for each window you want to open.

figure(1)
plot(1:10)
figure(2)
mesh(randn(10))

Before using plot() command you should place a "figure" command

For example:

clc; clear; close all;
t=0:0.1:10;
x=sin(2*pi*3.*t);
y=sqrt(t)+cos(2*pi.*t);
figure;
plot(t,x,'-b'); zoom on; grid on;
figure; 
plot(t,y,'-r'); zoom on; grid on;
