Use-case (Using BIRT version 2.2M2):

I created bar chart with the parameter - data set field binding name, so I
can specify row[parameter] for Y axis (values).

Question is: how to make proper sorting of bars from left to right in
descending order in simple bar chart?
I know I can sort the data set, but here it is not an option - in my case I
cannot sort data set because the field displayed by bar chart is a parameter
in report.
I also know I can pass another parameter for data set for sorting, but the
same data set is used for 2 charts and another sorting is already needed for
another chart on the same report.

It would be good to add sorting of result set for charts much like for report table. I think it is easy to add to chart just because it already exists for table. No need to add this new feature into the chart editing dialog (that may take a lot of time, I guess). Just allow specify sorting from properties pane for chart (like we specify sorting for report table).
