MATLAB: Multiple plot handles to the same figure

multiple handlesone figuresame figure

Hi,

I have two handles created with something like,

 hTri= trimesh();
 hFill= fill3();

where two figures act as parent's for hTri, say hTRiP, and the parent for hFill is hFillP.

I would now and then like to display both hTri and hFill in the same figur, say hTriP.

I've tried to set the 'Parent' and 'Children' properties for hTri and hFill, to hTriP. Either I'm doing something wrong or I'm in a blind of what to do… I do not wish to re-plot the figures, just show them both sometimes in the same figure, sometimes in two separate.

Thanks for any help!

Have you tried copyobj? you can use this to reparent a copy:

Use the figure handle:

 fgh = figure(...)

Using the handle you can set and get and properties of the figure (such as Position, Visible, etc), or delete it altogether. Note that all graphics objects have handles like this, and that if you want to write robust, fast code then you need to specify these handles explicitly:

 fhg = figure(...);
 axh = axes(fgh,...);
 lnh = plot(axh,...);

and then later you can much faster access their properties. Graphics objects and their handles are introduced very well in the documentation:

https://www.mathworks.com/help/matlab/creating_plots/graphics-objects.html

https://www.mathworks.com/help/matlab/learn_matlab/understanding-handle-graphics-objects.html

You will also find hundreds of tutorials online that introduce and explain graphics handles.

Note that every object has properties that you can access using this handle, e.g.:

https://www.mathworks.com/help/matlab/ref/figure-properties.html

My advice would be to use just one figure (or just a few), and access all of its component parts explicitly using their handles. Simply delete, add, replace, move, or update their values using their handles.

MATLAB: Combine three or more MATLAB figures

I would save figures then plot them as subplots like this:

%First Figure
h1 = openfig('test1.fig','reuse'); % open figure
ax1 = gca; % get handle to axes of figure
%Second Figure
h2 = openfig('test2.fig','reuse');
ax2 = gca;
h3 = figure; %create new figure
s1 = subplot(1,2,1); %create and get handle to the subplot axes
s2 = subplot(1,2,2);
fig1 = get(ax1,'children'); %get handle to all the children in the figure
fig2 = get(ax2,'children');
copyobj(fig1,s1); %copy children to new parent axes i.e. the subplot axes
copyobj(fig2,s2);
