Excel: plus minus graph

This is just a very nice and simple one:

Here are the data, from A1:B7:

2012	0
2012	1
2012	-1
2012	2
2012	3
2012	4
2012	-3

• format b1:b7 like this: 

"+";"-";""

which actually means:

+ above zero
- below zero
  zero

• Now create the column graph.
• Remove the X-axis
• Format the Y-axis like this:

"plus";"minus";"zero"

• add labels to the graph.
• columns below zero should get a different color by using: Invert if negative.
• change the minimum of the Y-axis to -5; and the maximum to 5.
• change the Major Unit to 5 as well.
