Accepted answer

You'll have to show your data to know for sure, but I think you have negative values in your data, so your domain looks like it goes from about [-600, 1800]. But when you calculate your width you first take the absolute value of your data, so your lowest possible value is 0. The solution is in your d3.extent accessor function, to evaluate the absolute value of your data (if that's actually what you want).
