subplot of already saved figures

i have somany figures like dyke_tap, dyke_tbp,dyke_tcp and dyke_tdp...... they aare all bar plots and i want to have them side by side in other to compare them. i have seen ways of merging them, but that wont be good for what i want so i want to use a subplot. how can i use a subplot on already saved figures..... example ' having 'dyke_tap, dyke_tbp,dyke_tcp and dyke_tdp' side by side

[David Sanchez]

what is the images extension? .fig? .png?

.fig

Here is a small bit of code that does just that for two saved figures. The figures need to be saved in the .fig format with this code (hgload only takes .fig figures as inputs), but there might be some way to adapt this code to make it work for other formats.

% Load saved figures
c=hgload('MyFirstFigure.fig');
k=hgload('MySecondFigure.fig');

% Prepare subplots
figure
h(1)=subplot(1,2,1);
h(2)=subplot(1,2,2);

% Paste figures on the subplots
copyobj(allchild(get(c,'CurrentAxes')),h(1));
copyobj(allchild(get(k,'CurrentAxes')),h(2));

% Add legends
l(1)=legend(h(1),'LegendForFirstFigure')
l(2)=legend(h(2),'LegendForSecondFigure')

[Iyk]

thanks for responding... I did that and it said "**********Error using copyobj Invalid handle**********"....

[Walter Roberson]

Try

copyobj(allchild(c), h(1))
copyobj(allchild(k), h(2))

[ismet saygu]

After you load saved figures (like c=hgload('MyFirstFigure.fig'); k=hgload('MySecondFigure.fig');), do not close the figure window

[Walter Roberson]

You can close the figure windows once the copying is done.

[Jingyun Yang]

The legends of the fig.s are lost. Is there any way to resolve that? Thanks.

[Walter Roberson]

To take into account colorbars, annotations, legends, and some more obscure constructs, a more complete method is needed. See for example https://www.mathworks.com/matlabcentral/answers/262265-duplicating-an-imshow-image-into-a-new-figure-without-using-imshow#comment_332459

I have a similar problem, but I am just plotting different simulation cases of the same data so I only need a single legend for all the variable I am plotting. Is there a way to get the legend to be on the 'northeastoutside' location like in a normal plot but for the entire subplot without messing with the size of any of the individual figures? I need to keep them the same scale for comparison purposes.

[Wenyi Xiao]

If my original figure are subplots, what should I do?

[Walter Roberson]

subplots are just axes.

You probably want to arrange each figure within a uipanel to frame it.

[Yunyu Hu]

This method works. But it does not copy the legend to the subplot

[Walter Roberson]

Which method were you using, Yunyu Hu? Did you follow to https://www.mathworks.com/matlabcentral/answers/262265-duplicating-an-imshow-image-into-a-new-figure-without-using-imshow#comment_332459 ?

[Farhad Sedaghati]

You can use the following function to insert all the saved fig files next to each other: http://www.mathworks.com/matlabcentral/fileexchange/51236-subplot

Hi, does it work for 3d graphs? I'm trying to use the code but it plots 2D graphs.

Thanks

[Tasos Ampelas]

Hi everyone,

In the @laurie 's first answer code, is there a way to get only the final figure and not every single one that I have loaded to matlab?

[Md Modassir Firdaus]

Hi everone,

You can try this code to create single figure having subplots. Here single plot is in subplot becouse it does not saved figure 1. First save the created plot then comment "savefig".

clc;
close all;
clear;
%%
z1=peaks;
z2=z1+randn(size(z1))/5;
figure(1)
surf(z1) %creating first figure 
savefig('PeaksFile1.fig') % save the figure once then comment it

%%%%
figure(2)
surf(z2,'FaceColor','r') %creating second figure
savefig('PeaksFile2.fig')% save the figure once then comment it

%% Loading saved above figure 
f1=hgload('PeaksFile1.fig');
f2=hgload('PeaksFile2.fig');

%% creating subplot
figure(3)
h(1)=subplot(1,2,1);
view(3)
grid on
h(2)=subplot(1,2,2);
view(3)
grid on
%%
copyobj(allchild(get(f1,'CurrentAxes')),h(1));
copyobj(allchild(get(f2,'CurrentAxes')),h(2));
