Consistent formatting in bar charts

[#1]

Description - Some of our bar charts are used for reporting into senior meetings. The formatting of the bar charts becomes inconsistent when nearing the top of the chart box and drops the legend of one bar to within the bar. It would be better to allow the chart box to be extended slightly to ensure that the formatting is consistent within the chart and all legends can sit above the bar.

Why is this feature important to you - Lack of consistency looks messy when used for reporting.

How would you like the feature to work - The legend on bar charts should be consistently above the bar they relate to. 

Current Behaviour - When a bar chart gets towards the top of the formatted chart box the legend moves to within the bar while others sit above.
