MATLAB: Multicolor bar graph using long vectors

barcolor

Hello,
I am trying to create a bar graph with one vector of positive numbers and one vector of negative numbers on the same graph. For example:
x = 1:100;
y = -(1:100);
bar(x,'b')
hold on
bar(y,'r')
This works fine!!
The problem is my vectors are 1370 x 1 variables and the same code does not work for long vectors…
x = 1:1370;
y = -(1:1370);
bar(x,'b')
hold on
bar(y,'r')
This creates blue bars for x, but creates black bars for y. Can anyone help me with this problem?!
Thanks, Dan

"black bars" usually means bars that are so close together that the black edge around them runs together.
Try using
bar(y, 'r', 'Edgecolor', 'none')
