I have a number of multi-series bar charts whose values are grouped into month-year categories. The layout mode is set to "Between" so that none of the information is clipped at start or end.
At the moment, the xcategory labels render at the center of each group of bars along the x-axis, where the major tick points would be (if we had them set to be visible).
What I want, is for the labels to render, not at the tick points, but at the major grid lines on either side of each group of bars. The idea is that it gives the impression that the values for the bar chart have occurred across a period or date range, with a start and end.
I've tried to illustrate what I am asking for in the image linked to below. Does anyone have any suggestions on how this could be achieved?
