Hello there. I'm using 'fill' to generate a series of polygons with [R G B] colour. The code is like this:

for i=1:n;
x=data(i,4:7);
y=data(i,8:11);
fill(x,y,[230/255 230/255 1]);
end

It always displays the coloured polygons with black edges. Anyone know how to hide the black edge or shall I use other functions say 'patch'? Many thanks!

Seb

fill creates a patch, so just record the handle returned by fill and set() the
EdgeColor property to 'none'.

Thanks a lot Walter. I tried to change the code as this:

for i=1:n;
x=data(i,4:7);
y=data(i,8:11);
f=fill(x,y,[230/255 230/255 1]);
set(f,'edgecolor',none,'facecolor',flat)
end

However it didn't return any visible polygons. Could you tell me what's wrong with that? Cheers

Sorry, changed it into set(f,'EdgeColor','none'), it works! Thanks!
