Have a column chart in which the same label applies to two adjacent columns. Rather than have it redundantly redisplay the labels I adjusted the tick mark spacing to 2 so it only displays every other label.

The problem is how to shift the alignment of the category labels along the x-axis to the label appears somewhat centered under the two columns to which it applies?

Normally I might trick something like this by adjust the the relationship of the displayed font to its baseline (similar to subscript or superscript functions). While I find the ability to choose subscript or superscript functions there is no ability I've found so far to adjust the extent of offset they accomplish and at the presets, they don't move the type very far, they just make it smaller.

Any ideas or workarounds appreciated.
