Displaying multiple figures using matlab

Question

I want to plot several figures on matlab using a for loop. I tried the following:

figure; plot(toDplot)

and

figure(2); plot(thing) figure(3); plot(something)

etc

But in both cases, my first plot is replaced by the next one...

Why is it replacing the first frames?

so you're using figure(x) inside the for-loop? but always with the same number x? Use a different number every iteration and it will create a new figure, or use hold on behind the plot command, to plot multiple graphs in the same figure. — Robert Seifert

I'm using figure(k) (when I loop on k). I also tried with hold on but it plots me the different curbs on the same plot and I want each curb to be plotted on a different figure — bigTree

So you end up with lots of empty figures and only one with your plot? — chappjc

If you type in the command window the following: close all; figure; figure;, does it create 2 figures? — marsei

Your new figures are not taking over as the current figure (gcf).

To explicitly specify where a plot will go, you can call it with the syntax plot(HA,...). From the MATLAB docs:

plot(axes_handle,___) plots into the axes specified by axes_handle instead of into the current axes (gca)

To use this, you would make a figure and axes, storing their handles, like so:

hf = figure; ha = axes('parent',hf); plot(ha,x,y)

P.S. I just saw that you got it to work by putting a close all before your loop! I'll keep the answer here for reference since it is a good way to be explicit with your plotting.
