Saving an image from subplots in a uipanel

I am running a live system that is controlled via a complex figure. One part of this figure is a uipanel (named handles.APlot) that contains three subplots - so:

    subplot(311, 'Parent', handles.APlot);
    handles.plotx=animatedline('Color','b','LineWidth',1);
    ylabel('x (m)');
    xlabel('time (s)');
    subplot(312, 'Parent', handles.APlot);
    handles.ploty=animatedline('Color','b','LineWidth',1);
    ylabel('y (m)');
    xlabel('time (s)');
    subplot(313, 'Parent', handles.APlot);
    handles.plotz=animatedline('Color','b','LineWidth',1);
    ylabel('z (m)');
    xlabel('time (s)');

This is continually updated until the end of a run:

   hold on;
   addpoints(handles.plotx,timeelapsed,X_mean);
   addpoints(handles.ploty,timeelapsed,Y_mean);
   addpoints(handles.plotz,timeelapsed,Z_mean);
   hold off;

where timeelapsed is the time after start in seconds and the three means are positions in X, Y and Z. At the end of a run we get three nice graphs showing the events in X, Y, Z during the run.

My question is: How can I save these graphs to a file? A uipanel is not a figure so I can't access a frame. Matlab seems to indicate that there is an internal figure generated when you place axes(subplots) on a uipanel, but I can't find any way to access this.

You could copy the axes objects to a temporary figure.

   name={'plotx' 'ploty' 'plotz'};
   pos=getpixelposition(get(handles.(name{1),'Parent');
   new=figure('Units','pixels','Position',pos);
   for n=1:numel(name)
      copyobj(handels.(name{n}),new);            
   end
   print(new,'-dpdf','myplots.pdf');
   delete(new);

A minor modification and it worked perfectly - thank you.

name={'plotx' 'ploty' 'plotz'};
pos=getpixelposition(handles.APlot');
newfig=figure('Units','pixels','Position',pos, 'Visible','off');
for n=1:numel(name)
    copyobj(handles.(name{n}),newfig);            
end
saveas(newfig, 'PlotXYZ.jpg');
delete(newfig);
