How can I save UIAxes as an image when button is pushed in app designer?

How can I save UIAxes as an image when button is pushed in app designer?

 newfigure = figure;
 copyobj(app.UIAxes, newfigure);
hgsave(newfigure, 'testFIgure.fig');

I tried this but it gives me an error.

Which MATLAB release? It has only become possible in R2020a, not before.

[Yaren Sever]

2020 release. I solved the problem but now when I push the button, XLabel, YLabel and Title of the UIAxes dissappears. Do you have any idea about this?

% Create new axis

newAxes = axes;

% Copy all objects from UIAxes to new axis

newAxes.Title= app.UIAxes.Title;

newAxes.XLabel = app.UIAxes.XLabel;

newAxes.YLabel = app.UIAxes.YLabel;

copyobj(app.UIAxes.Children, newAxes)

fig2Save = ancestor(newAxes, 'figure');

fig2Save.Visible='off';

%dialog box,save as

filter = {'*.jpg';'*.png'}

[filename, pathname] = uiputfile(filter);

newfilename = fullfile(pathname, filename);

saveas(fig2Save, newfilename);

I solved whole problem:

figure;

% Create new axis

newAxes = axes;

% Copy all objects from UIAxes to new axis

newAxes.Title= app.UIAxes.Title;

newAxes.XLabel = app.UIAxes.XLabel;

newAxes.YLabel = app.UIAxes.YLabel;

copyobj(app.UIAxes.Children, newAxes)

%in order to keep titles and labels on uiaxes

xlabel(app.UIAxes, newAxes.XLabel.String);

ylabel(app.UIAxes, newAxes.YLabel.String);

title(app.UIAxes, newAxes.Title.String);

fig2Save = ancestor(newAxes, 'figure');

fig2Save.Visible='off';

%saveas(fig2Save,'myfigg.png')

%close(fig2Save);

%dialog box,save as

filter = {'*.jpg';'*.png'}

[filename, pathname] = uiputfile(filter);

newfilename = fullfile(pathname, filename);

saveas(fig2Save, newfilename);

Try exportgraphics().

[Walter Roberson]

Which, by the way, is new in R2020a.

[Image Analyst]

If you don't have that, then give export_fig a try:

[Adam Danz]

The code you shared shows that you're exporting the children of a UIAxes onto a regular axis.

That can be done with copyUIAxes() from the file exchange, even on Matlab releases prior to 2020. That function avoids the problem of disappearing axis labels.

[zsh fardi]

Hi. Why is copyUIAxes() undefined in Matlab R2021a?

[Image Analyst]

@zsh fardi Because it's a third party function written by Adam. It's not part of base MATLAB. You have to download it, and if it's not in your current folder, use the "Set Path" button on the Home tab of the tool ribbon to add its folder to the path.
