MATLAB: Error using subplot, cannot set property to a deleted object

axesMATLABplottingsliceviewersubplot

I am wanting to plot two figures side by side.

I am wanting to plot the output of sliceViewer from a 3d object that I have and this is what I have attempted

figure(2);
subplot(1,2,1)
sliceViewer(G1,'Colormap',cmap);
subplot(1,2,2)
sliceViewer(G2,'Colormap',cmap);

Which gives me this error

Error using axes
Cannot set property to a deleted object
Error in subplot (line 602)
        ax = axes('Units', 'normalized', 'Position', position, ...
Error in Deconvolve3d2 (line 94)
subplot(1,2,2)

I think it is something to do with how sliceViewer displays its outputs and it is somhow deleting the axes for the subplot

Thanks

sliceViewer deletes the axes of its parents, so you cannot put it into a subplot.

However, sliceViewer can be put into a uipanel. Therefore you can create a uipanel beside your other graphics axes, and specify the uipanel by passing the 'Parent' option to sliceViewer()

MATLAB: Clearing Subplots & getting the original view

subplot() does not "split" or subdivide an existing axes. subplot() uses its parameters to figure out where on the figure the desired axes should be positioned. Then subplot looks at all over the other axes in the figure, and if it finds that any of them would be covered over by the new axes, then it deletes the old axes. So if you had

plot(rand(1,20))
subplot(1,2,1)

then the subplot() would notice that it was covering over the axes that had the plot() in it and it would delete the old axes, and the plot would be gone.

Thus, if you want to restore back to the single axes after you have done a subplot(), you need to create it again.

There is a way to save the content of an axes and restore it later. Two ways, actually:

1) You can use hgsave() and later hgload() to save the object in a .mat file and restore a copy of it when needed. This is not usually done except when creating .fig files; OR

2) You can create a figure whose visibility is set off, and set the Parent property of the axes to be the new figure. This will preserve the axes and contents exactly as-is, just not visible. Later when you want to restore it, you can set its Parent property back to be the original figure. You can hide any number of objects in the same invisible figure. Keep in mind, though, that the saved objects take up memory.
