Manhandling the REFRESH function?

Is there anyone out there who knows of a way of altering the way a
figure is refreshed? I have been developing some M-files for placing
labels on the lines of a contour plot (similar to the "extcontour"
package). The package (as is) allows use of the mouse to select the
placement of these labels along a line, WITHOUT removing data from
the contour description matrix (the points defining the lines).

Instead of altering the contour description matrix I had planned on
using the patch function to remove a piece of contour line so as to
add a line label. However, I have found that after adding a couple of
line labels in this way, lines are drawn over some of the existing labels
in what appears to be a very random way. It turns out that I have never
been able to get more than about 70% of the labels added properly (i.e.,
without lines drawn through them). I am assuming that the way a figure
is refreshed is responsible for this problem.

So back to my question: Is there a way of telling the refresh function
to not redraw/refresh certain objects? I've already tried (in vain) using
the following properties (none of which I know much about).

set(axes_handle,'Layer','top'); %% I couldn't find any documentation
%% on this property, so I tried it!

Thanking you,
