Currently when sorting bars by value in a bar chart, the sorting is based on the total bar value. Please add an option to customize the value to sort on.
Example:
I've a barchart with on the category axis different customers. On the value axis I've the sums of the expenditures for different categories (e.g. sum(electronics), sum(food), sum(furniture), etc).
Currently when I choose to sort bars by value they are sorted by the sum of all expenditures. I want to be able to sort the bars by sum(electronics) or maybe by a ranking column, or something else :)
