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 onbar(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 onbar(y,'r')`

This creates blue bars for x, but creates black bars for y. Can anyone help me with this problem?!

Thanks, Dan
