Hello everyone,

I'm trying to plot several findchangepts plots as subplots in a single figure. I found it can't be done unfortunately.

Do you have any idea how to do so? any workaround?

Kindly check the attached .mat file. Here's what I need to plot.

subplot(3,1,1) 
findchangepts(B,'MaxNumChanges',5); 
subplot(3,1,2) 
findchangepts(Bz,'MaxNumChanges',5); 
subplot(3,1,3) 
findchangepts(Dst,'MaxNumChanges',5);

Take a look at the find change points live task which will generate the code for you for the plot you're looking for. Copy and paste it into subplot (or tiledlayout!)

Tiledlayout was added in 19b. The same logic would work with subplot.

I work on R2017b. I disabled these two lines t = tiledlayout(3,1); nexttile(t) And I wrote this line t = subplot (3,1,ii); Inside the for-loop, and it works :) Thank you!

Hello,

the ischange function does not have two types of methods which findchangepts has such as 'rms' and 'std'. How to use subplot and findchangepts with these two methods?

thank you....
