My code is able to save the axes1 plot but legend is missing on the saved file. Any help to get legend in the saved image? Any other method appreciated. I do not want to use export_fig. Using Matlab 2014a.
[filename,pathname] = uiputfile('*.jpg;*.png;*.tif','Save as');
if pathname == 0 %if the user pressed cancelled, then we exit this callback
return
end
haxes=handles.axes1;
ftmp = figure('visible','off');
new_axes = copyobj(haxes, ftmp);
set(new_axes,'Units','normalized','Position',[0.1 0.1 0.8 0.8]);
saveas(ftmp, fullfile(pathname,filename));
delete(ftmp);

This is expected behavior because the axes object does not save an associated legend. You will need to make a separate call to "copyobj" on a legend to copy a legend to your new figure. The following code snippet illustrates this (toggle the "copyLegend" variable to determine whether the legend is copied):
close all;
copyLegend = true;
plot(1:10);
hleg = legend('myplot');
hax1 = gca;
ftmp = figure;
new_axes = copyobj(hax1,ftmp);
if copyLegend
copyobj(hleg,ftmp);
end
A legend will only appear on Figure 2 if "copyLegend" is set to true.
