patch with "Edges have no color"

[Andre Valente]

Hi all,

I want to plot a figure like the one in attachment. I can't seem to do it in octave. Using matlab I use patch:

x=[1 2 3]
y=[1 2 3]
z=[0.1 0.2 0.3]
figure
p=patch(x,y,z,'MarkerSize',25,'Marker','o','MarkerFaceColor','flat','FaceColor','none');
set(p,'EdgeColor','none')
caxis([0 0.5]);

Can anyone help me? Thanks!

Cheers,
Andre
