pcolor + contour |

With 3.0, the following code seems to overlap contour on pcolor correctly:
octave:> pcolor(z);shading flat; hold on
octave:> contour(z);
However, I have a real data set, but just cannot show the contour line with
the following code:
h1=pcolor(d1); shading flat; hold on;
[c2,h2]=pcolor(eps,1); % with colormap(jet)
where d1 is a 60x120 intensity map with magnitude ranging [0 5] and eps is
same size map with bottom half being 1 and upper half being 2.3 (just like a
half plane so I only need one contour to see the separation).
I can not see the contour even by using
set(h2,"edgecolor","white");
BUT, if I do [c3,h3]=contour(d1), then immediately both contour for d1 and
eps show up. Then, I can set the edgecolor of h2 to whatever I want.
This may be a workaround if I can delete the contour of d1 (h3). I tried to
delete(h3), but it didn't work either. So I am stuck.
Thanks for your help!!
