Adding multiple function plots to a single figure with subplots - MATLAB

I've been trying to run a function three times that plots 2 sub-plots (6 plots total) onto on singular figure.

So I've got a function that reads in a dataset and a manipulator, then manipulates it in 2 different ways, then plots in 2 subplots - the function works as it should, I just can't seem to merge the plots when I'm running it in a seperate script.

Simplified function below:

function function_plot(dataset,manipulator)
%Manipulates Data
figure;        
subplot(1,2,2);
imagesc(data_manipulated1);
subplot(1,2,1);           
imagesc(data_manipulated2);    
end

Simplified script below:

function_plot('data.mat',manipulator1);
function_plot('data.mat',manipulator2);
function_plot('data.mat',manipulator3); 

I've also tried the below - but this gives the error "Too many output arguments"

function function_plot(dataset,manipulator,myfigure)
%Manipulates Data
if nargin<4 
    myfigure = figure;
else
    figure(myfigure); 
end   
subplot(1,2,2);
imagesc(data_manipulated1);
subplot(1,2,1);           
imagesc(data_manipulated2);    
end

Simplified script:

myfigure = function_plot('data.mat',manipulator1);
function_plot('data.mat',manipulator2,myfigure);
function_plot('data.mat',manipulator3,myfigure);

To be clear, you want three outputs of imagesc overlaid on one subplot and three outputs of imagesc overlaid on the other subplot?

Answer 1

[Star Strider]

I am not certain what you intend by 'merge the plots'.

Note that you need to load a .mat file to use its contents. Consider loading into a variable, creating a structure that you can extract data from in its fields.

Also, consider using the hold function, if appropriate.

This might be what you want:

Manipulators={manipulator1,manipulator2,manipulator3};

m=3;n=2; %tiling dimensions

%create handles
figure;  
ax=gobjects(n,m);
for i=1:m*n;
    ax(i)=subplot(m,n,i);
end
ax=ax';

%populate the axes
for j=1:3  
 function_plot(ax(j,:),dataset,Manipulators{j});
end

function function_plot(ax,dataset,manipulator)     

 imagesc(ax(1), data_manipulated2);   

 imagesc(ax(2), data_manipulated1);
 
end
