In case when border is set for stacked bar, then is cutted of in the edge.
Workaround is set max as 100.1 and endOnTick as false.
In the new revised column layout as of today (2013-08-23), the one pixel column border will be clipped away as it lies exactly on top of the top grid line. This may be wrong - the ideal solution may be to show the column border if there is only a grid line (as grid lines have lower Z index), but let it be covered by Axis line and Plot line.
This is still relevant, and I would consider it a bug. The border should have a higher z-priority than grid lines
Agree, border should be shown without some worakarounds.
