Let Us Reverse Stacked Bar Chart Legend Order

We should be able to reverse the order of the legend in a stacked bar chart.

Currently, the stacked bar chart puts the first field you've selected for the Y-axis at the top of the legend, and subsequent fields below. Conversely, on the chart itself, it puts the first field you've selected at the bottom, and stacks upwards from there.

It makes the charts confusing because the legend and actual data do not correspond at all. We should have more control over the sorting of the legend, either to reverse it, or arrange it freely (i.e. to put the most important legend item at the top, although that's more important for combo charts).

None of the charts give you control over this aspect. They all should.
