Hi, I am using MATLAB R2020a on a MacOS. I have specified the production of a graph within a 'for' loop but when I run the code, only the graph for the last run of the loop is displayed. I don't want to store all the vectors for each loop due to storage constraints and instead, the values in the vector are overwritten with each run of the loop.

Is there any way of displaying the graphs for all runs of the loop rather than just the last one?

Any suggestions would be much appreciated. Thanks in advance.

for currentcycle = 1:length(number_cycles)

if currentcycle > 1

% If comparison between raw v and w co-ordinates and previously

% accepted exponentially weighted moving mean meets condition

current_expmean_v = (1 - 1/weight(currentcycle))*(previous_expmean_v) + (1/weight(currentcycle))*(values_v);

current_expmean_w = (1 - 1/weight(currentcycle))*(previous_expmean_w) + (1/weight(currentcycle))*(values_w);

plot(values_v, values_w, previous_expmean_v, previous_expmean_w);

xlabel('v (mV)')

ylabel('w (mV)')

title('2D phase space trajectory of current cycle and exponentially weighted trajectory of previous cycle');

previous_expmean_v = current_expmean_v;

previous_expmean_w = current_expmean_w;

% If condition is not met, previous_expmean is not updated but

% remains the same and warning message is presented

end

end

figure

hold on

<LOOP>

hold off

If you are plotting single points in each loop iteration (not possible to determine that from the posted code), plot a marker (or use the scatter function) rather than expect a line, since lines are only drawn between elements of vectors with elements presented to the plot function in each call to it.

As always, my pleasure!

The subplot version should produce 1 figure window with 3 plots. It would be figure(4) with my code:
