After using MATLAB live script, I noticed that when I create figures, the numbering does not increment by 1 as expected. Instead, it skips figures 2 to 4. For example, if I write the code in live script:
figure
figure
figure
the output will be figures 1, 5, and 6. How can I resolve this problem?

Hi @Ahmad,
I recommend putting the following command:
close all
at the beginning of your MATLAB live script. This should reset the figure numbers before the rest of the script is run. Alternatively, you can manually assign numbers to your figures however you like:
figure(1)
figure(2)
figure(57)

Thank you Mr. Austin for your help. I am attempting to create two separate figures in the MATLAB Live Editor, but the plots are being displayed together in a single figure. Note: I defined Num since I can't create figure(1) for some reason, although restarting MATLAB resolved the issue but executing the code several times causes this issue. Here is snapshot of my code.
clc;clear;close all
.
.
.
hfig = figure;
Num=hfig.Number;
for var3=1:numel(d)
fig1=figure(Num);
hold on
plot(VTh,reshape(WsMax(:,1,var3),1,[]))
title('plot 1');
xlabel('VTh');
ylabel('Ws');
hold off
fig2=figure(Num+1);
hold on
plot(VDC,reshape(WsMax(1,:,var3),1,[]))
title('plot 2');
xlabel('VDC');
ylabel('Ws');
hold off
end

I have come across the same issue in the past where I would execute a block of code in an .mlx file and then the plots would get combined. The solution that I have found for this is to separate the figures into separate blocks using a section break (%%):
hfig = figure;
Num=hfig.Number;
for var3=1:numel(d)
fig1=figure(Num);
hold on
plot(VTh,reshape(WsMax(:,1,var3),1,[]))
title('plot 1');
xlabel('VTh');
ylabel('Ws');
hold off
end
%% Start new section here
for var3 = 1:numel(d)
fig2=figure(Num+1);
hold on
plot(VDC,reshape(WsMax(1,:,var3),1,[]))
title('plot 2');
xlabel('VDC');
ylabel('Ws');
hold off
end
Note that in .mlx files you might run into problems trying to execute a for-loop across multiple sections, so I split your code into two for-loops. You can adjust this however you need. Hopefully you can get your script to work now.
Alternatively, you can try running your code in a normal script file (.m) instead of a live script file.

Initially, the .mlx file was working fine, but later on, it only displayed one figure while the other was missing. however, everything runs smoothly in the .m file.
