Plotting a line on same axes as pcolor in GUI

I'm trying to plot a line on top of my color plot in a GUI made in GUIDE. I would typically use the "hold on" command, but this doesn't work in GUI. Or I would plot(x,y1,x,y2) for two lines. Here's what I've got so far:

p = handles.pAxes;

h = pcolor(p,x,Vi,dos');

set(h,'edgecolor','none')

shading(p,'interp');

colormap(p,'cool');

plot(p,x,vpot);

xlabel(p,'x (A)');

ylabel(p,'E (eV');

Doing this the (x,vpot) plot simply replaces pcolor. Halp!

hold(handles.pAxes,'on');
