In barcharts, the order of items in the legend (key) is reversed from the order in which they are displayed in the stacked bar chart -- the top item in the legend is the bottom item in the bar.  It would be much easier to read if they were displayed in the same order.

Steps to reproduce:
1. Reports -> Assets & Liabilities -> Asset Barchart  (or any other barchart, such as Income or Expense barcharts)

Actual results:
The bottom item in the stacked bar chart appears as the top item in the legend.

Expected results:
The bottom item in the stacked bar chart should be the bottom item in the legend.

Does this happen every time?
Yes.
