How to put existing figures in one figure together?

I have two existing figures ('fig1.fig" and "fig2.fig"), and want to put in one figure together horizontally and vertically (creating 2 figures).

I tried to use "tiledlayout" spending some time, but failed.

Thank you very much,

openfig('fig1.fig')

ans = 
  Figure (1) with properties:

      Number: 1
        Name: ''
       Color: [1 1 1]
    Position: [268.2000 671.0000 560 420.0000]
       Units: 'pixels'

  Use GET to show all properties

openfig('fig2.fig')

ans = 
  Figure (2) with properties:

      Number: 2
        Name: ''
       Color: [1 1 1]
    Position: [1325 496 560 420]
       Units: 'pixels'

  Use GET to show all properties

% open the fig files in two new figures
f1 = openfig('fig1.fig','invisible');
f2 = openfig('fig2.fig','invisible');

% get the ConfusionMatrixChart in each figure
cmc1 = f1.Children;
cmc2 = f2.Children;
% alternate way to get the ConfusionMatrixChart in each figure
% cmc1 = findall(f1,'Type','ConfusionMatrixChart');
% cmc2 = findall(f2,'Type','ConfusionMatrixChart');

% create a new figure with a tiledlayout
f = figure();
t = tiledlayout(f,1,2);
% copy the charts into the tiledlayout
h1 = copyobj(cmc1,t);
h2 = copyobj(cmc2,t);
% place them correctly
h1.Layout.Tile = 1;
h2.Layout.Tile = 2;

% same thing, now with a vertical layout

% create a new figure with a tiledlayout
f = figure();
t = tiledlayout(f,2,1);
% copy the charts into the tiledlayout
h1 = copyobj(cmc1,t);
h2 = copyobj(cmc2,t);
% place them correctly
h1.Layout.Tile = 1;
h2.Layout.Tile = 2;

% delete the original figures
delete([f1 f2])

Perfect!

Thanks a lot!

You're welcome!

Here's one way to have one xlabel and one ylabel:

% open the fig files in two new figures
f1 = openfig('fig1.fig','invisible');
f2 = openfig('fig2.fig','invisible');

% get the ConfusionMatrixChart in each figure
cmc1 = f1.Children;
cmc2 = f2.Children;
% alternate way to get the ConfusionMatrixChart in each figure
% cmc1 = findall(f1,'Type','ConfusionMatrixChart');
% cmc2 = findall(f2,'Type','ConfusionMatrixChart');

% create a new figure with a tiledlayout
f = figure();
t = tiledlayout(f,1,2);
% copy the charts into the tiledlayout
h1 = copyobj(cmc1,t);
h2 = copyobj(cmc2,t);
% place them correctly
h1.Layout.Tile = 1;
h2.Layout.Tile = 2;
% set both charts xlabel and ylabel to ''
xlabel([h1 h2],'')
ylabel([h1 h2],'')
% apply the xlabel and ylabel to the tiledlayout itelf
xlabel(t,'Predicted Class')
ylabel(t,'True Class')

Even more perfect!

Thank you for the bonus!

If subplot layout is acceptable, then ...

% open the fig files in two new figures
f1 = openfig('fig1.fig','Invisible');
f2 = openfig('fig2.fig','invisible');

hnew = figure;
ax1 = copyobj(f1.Children,hnew);
subplot(2,1,1,ax1)
ax2 = copyobj(f2.Children,hnew);
subplot(2,1,2,ax2)

[Mibang]

Perfect, again! This is even simpler.

Maybe bonus for me: is it possible to make the labels simpler, i.e., one "True Class" and "Predicted Class"?

Maybe not possible

I want this answer accepted too, but I cannot.

Thank you very much.
