Text and Line only shown in debug mode

Hi,
I am making a GUI. Inside it, I have placed an axes. I am writing a text label and a line, creating a text and a line objects. When I set a breakpoint in the text() or line() functions, the objects are correctly drawn in the axes, but not when I run the script. I am using Matlab R2011a.
Thanks, Luis

Maybe add drawnow command after you draw the line, or try to use refresh function.

Avoid to use "ylim" as name of a variable, because it is a built-in function. But this is not the cause of the problem.
The low-level function LINE needs the property name for the parent:
line('Parent', handles.myAxes, [a;a],ylim,'linewidth',2,'color',[0,0,0]);
You can obtain the handles of the line or text object and check it in non-debug mode:
H = line(... your calling sequenc...)
disp(get(H, 'Parent') == handles.myAxes)
Then you will find out, that the line is drawn to another AXES object. Therefore the specification of the Parent should solve the error.

You will probably need to put the 'Parent' parameter _after_ the positional parameters, as in
line([a;a],ylim, 'Parent', handles.myAxes, 'linewidth',2, 'color',[0,0,0]);
