Dirty way:
cla(axes_handle)
If you know the handle of the line:
if ishandle(line_handle)
delete(line_handle)
end
if you don't know the line handle, use get(axeshandle,'Children') to find it.

Hi!
I want to do the same, delete a line if exist in a plot in a fuction.
I used the suggeste code
if ishandle(line_handle)
delete(line_handle)
end
But I got the error:
Undefined function or variable 'line_handle'.
How can I fix it?!
