Open figure in new window instead of next to editor using figure object

I haven't been able to work out how I can force Matlab to open a figure in a new window using the figure object (using online version at the moment: https://matlab.mathworks.com/).

The following answer only seems to make it visible or invisible but not opening in a new window: https://www.mathworks.com/matlabcentral/answers/307121-how-to-force-an-external-figure-in-live-scripts

% Opens next to editor (Without taking the size parameters):
f1=figure;
f1.Name = 'FFT-Test';
f1.Position=[150,0,1000,650];

% Opens in new window:
figure('Name', 'FFT-Test','position',[150,0,100,650])

Any ideas?

To clarify here two screenshots:

(as you can see, if I want more than one plot in the same figure, I can make the figure window a lot bigger and see more detail, if it opens in a separate window)

I can't understand what you want

I have added 2 screenshots to my question, to clarify my problem (you may have to scroll to the right to see the full pictures).

Answer 1

%%
close all;
f=figure('Name', 'FFT-Test','position',[150,0,1000,650])

f1=subplot(4,1,1,'Parent',f)
plot(1:10)

f4=subplot(4,1,4,'Parent',f)
plot(rand(10))

Great, this solution works. Thanks a lot!
