Column Chart - columns overlapping Y axis

[Reddog94]

I have eight data points in a column graph, ranging from -13.9% to +4.5%. The Y axis of zero is in the middle of the chart. The columns overlap the Y axis, and this overlap grows as the column width is increased. At a 1 column width, there is no overlap. At a width of 5, there is a light overlap, and it grows from there.

I have tried changing the chart type, and every setting I can find with no luck. Anyone have any ideas to make the columns just start at zero and not overlap the y axis??
