bar plot loses edge colour

Hi,

I am trying to plot a bar graph but the edge colour of the bars is not showing up. If i plot anything except the full matrix (ie bar(A(2:end,:),'stack') or A(1:end-1,:)) then the edge color is showing up fine. The matrix A has a lot of zeros in it which I think might be causing the trouble.

for example: this is the result from bar(A,'stack'):

whereas this is the result from bar(A(2:end,:):

Can anyone shed some light onto why this is happening? I tried forcing the edge colour ( 'EdgeColor','k','LineStyle','-') but this didnt fix it. I am using 2014a

Thanks very much!

That's the default behavior when the amount of data gets too large. The thinking was that all of those black lines would clutter the picture up. You can override it by explicitly setting the EdgeColor like this:

h = bar(A,'stack')
set(h,'EdgeColor','black')

I think that the magic number is somewhere are 150. How many values are in A?

I'm not sure why setting the EdgeColor at the end of the bar command didn't work.

Hi, Thanks very much, that sorted it out! The default behaviour does make sense, I wasnt aware it did anything clever like that. Knowing that using set(h,...) has a different behaviour than changing it in the bar command is useful, im sure that would have solved some of my other problems I had a while back!
