Thread Subject: Warning: Patch FaceVertexCData length question...

The following works for 1 <= n <= 150 and fails for any n>150. What do I
need to do to fix this?

The basic goal is the color any positive value red and any negative value
blue.

function test(n)
xaxisv = 1:n;
anom = random('norm',0,1,1,n);
barH = bar(xaxisv,anom);
barC = get(barH,'Children');
set(barC,'CDataMapping','direct');
mc = [0 0 1;1 0 0];
nv = 1*(anom<0);
pv = 2*(anom>=0);
index = nv+pv;
set(barC,'CData',index);
colormap(mc)

Thanks!
Bruce
