Hey guys,

I'm trying to make a graph (bar chart) that has it's centre point around 1. Basically, rather than the x axis intercept bet at 0 I'd like it to be at a single point which counts for +1 or -1. Thus negative values begin at -1 and decrease from there, or positive values begin at 1 and continue from there.

For example:

My negative values could be:

-1.05
-1.1
-1.5
-1.69
-1.9
-4

My positive values could be:

1
1.05
1.4
1.6
1.7
5

Thanks in advance.
