Get access to Marker handle of a line plot

I trying to get acces of the "MarkerHandle" of a line plot:
h_plot = line(x,y); hMarkers = get(h_plot,'MarkerHandle');
It works great in case I am running the code in debug mode. Unfortunatelly, running the program in "normal" mode, I don't get access to the handle (results in "0×0 empty GraphicsPlaceholder array"). Any ideas?

Sounds like a concurrency issue to me. Did you try with an intermediate "drawnow"?

While using the line function try to mention the marker as the input to the function,
e.g:
h_plot = line(x,y,'Marker','o')
And then try to access the hMarkers =
get(h_plot,'MarkerHandle');

Matlab optimisation somehow destroys proper marker definitions.
Hack-solution: pause between creating the plot and fetching the markers.
h_plot = line(x,y);
pause(0.0000000001);
hMarkers = get(h_plot,'MarkerHandle');
