my_fig.jpg

Hello,

I have the attached figure. It has:

xlabel & ylabel
xAxis & yAxis
title
grid
colorbar
surf (x,y,z) plot

I have handle to this figure in my code.

How can I insert ALL_OF_IT into my GUIDE (GUI) axes object?

I've tried to use copyobj, BUT:

it copies only the surf map itself (with some wired change of colormap... but I suppose I can live with that).
I don't know how to copy also all the other stuff (xlabel , title , color bar , etc...)

I've tried to save my figure as an image file (tiffn), and then load it (imread) onto the axes. It works basically, but it makes it in a very poor/small resolution.

Also, I want to be able to shift it back from my GUI axes to an external figure. So having it stored as an image on my axes is far from optimal (I'd like to be able to zoom, go over data points, etc...)

Any Ideas?

THANKS !!!

fig1 = figure();

surf(ax1, X, Y, Z, 'edgecolor', 'none');

xlabel(ax1, 'x');

ylabel(ax1, 'y');

colorbar(ax1);

grid(ax1, 'on');

title(ax1, 'This is the original');

fig2 = figure();

copyobj(fig1.Children, fig2)

ax2 = gca(fig2);

title(ax2, 'This is the copy')

Notice that the copyobj was on the children of the figure, not of the axes. colorbar in particular is not part of the axes. title and labels are not children of the axes, they are properties of the axes. This causes complications.

%creating source to copy for demo purposes

heatMapFigHandle = figure('Name', 'original');

ax1 = axes(heatMapFigHandle);

[X, Y] = meshgrid(linspace(-5,5,50));

Z = tan(X).*cos(Y);

surf(ax1, X, Y, Z, 'edgecolor', 'none');

xlabel(ax1, 'x');

ylabel(ax1, 'y');

colorbar(ax1);

grid(ax1, 'on');

title(ax1, 'This is the original');

%creating destination to copy to for demo purposes

twoD = figure('Name', 'Destination GUI');

handles.twoD_axes = axes(twoD);

%if this was not a demo you would have instead called

%{

heatMapFigHandle = plotWM(heatMap_inputMat , '3 Sigma per site'); % this is my fig_1 handle

%}

twoD_figure = ancestor(handles.twoD_axes, 'figure');

HM_ax = gca(heatMapFigHandle);

%what can be written?

copy_details_only = {'Title', 'XLabel', 'YLabel', 'ZLabel'};

copyable_properties = setdiff(fieldnames(set(HM_ax)), ...

[{'Children', 'Parent', 'XAxis', 'YAxis', 'ZAxis'}, copy_details_only]);

%clone properties

set(handles.twoD_axes, copyable_properties, get(HM_ax, copyable_properties));

%copy the things that are inside the axes

copyobj(HM_ax.Children, handles.twoD_axes);

%colorbars have to be copied with axes, but we are not copying axes

cb = findobj(heatMapFigHandle, 'type', 'colorbar');

if ~isempty(cb)

copyable_properties = setdiff(fieldnames(set(cb)), {'Children', 'ContextMenu', 'Parent' });

twoD_cb = colorbar(handles.twoD_axes);

set(twoD_cb, copyable_properties, get(cb, copyable_properties));

end

%text objects have to be copied, otherwise they disappear from original

for K = 1 : length(copy_details_only)

propname = copy_details_only{K};

srcobj = HM_ax.(propname);

destobj = handles.twoD_axes.(propname);

copyable_properties = setdiff(fieldnames(set(srcobj)), {'Children', 'Parent'});

set(destobj, copyable_properties, get(srcobj, copyable_properties));

end

The second one is not really the original... the title got copied too, as you requested.

@Walter Roberson

Thank you for the detailed response, but unfortunately it didn't work. Few questions/remarks:

ax1 & HM_ax are the same, right? I got error for ax1 ("output has too many arguments"... MATLAB 2015b). Anyway, you don't use ax1 anywhere down the code...

set(twoD_cb, copyable_properties, get(cb, copyable_properties));

gave me the following error:

Error using matlab.graphics.illustration.ColorBar/set
The UIContextMenu's parent figure is not the same as the parent figure of this object

Eventually, all those lines of code somehow made my 2D axes on the gui layout to disappear, and be translated to some small bottom-left corner... in some weird way... please see image below (marked with Blue pen):

I don't know if it's related, BUT, can you please create an example where the following conditions exist:

source is a stand alone figure (with 'Visible' set to 'off'... not crticial of course, I can make it visible again if required) - you can see an example in my attached file: my_fig.jpg
destinated is an axes object, which is part of a MAIN GUIDE figure, for the sake of the example it's handle called: handles.twoD_axes (I mean it's axes type object that I drag & drop onto my GUIDE GUI main figure pallate.

All I want to do, is a FULL copy-paste of ALL contents of my source FIGURE into my destinates axes.

CAN this be done? Do I need to configure something before that? Maybe units type or something like that? I don't know...

thanks, I've got exactly the result I wanted with the following code:

heatMapFigHandle = plotWM(heatMap_inputMat , '3 Sigma per site'); % my figure handle
heatMap_ax = gca(heatMapFigHandle);                               
cla(handles.twoD_axes , 'reset')
    
colormap(handles.twoD_axes , 'jet')
copyobj(heatMap_ax.Children, handles.twoD_axes);
colorbar(handles.twoD_axes)

When you do that, the properties of the axes such as the labels and limits and axis direction and view do not copy over; also any special colormap customization will not get copied.
