Hi Adam,
In the below example, first you need to copy the UIAxes to the temporary figure. And then you can save it as *.png.
function saveplot_Callback(app, event)
% Create a temporary figure with axes.
fig = figure;
figAxes = axes(fig);
% Copy children (lines).
copyobj(app.UIAxes.Children, figAxes);
% Copy titles and labels. You can modify this based on your requirement.
copyobj([app.UIAxes.XLabel app.UIAxes.YLabel app.UIAxes.Title], figAxes);
% Save as *.png file.
saveas(fig, 'myFigure.png');
close(fig);
end
