To develop manual sorting in graphs

There is a possibility of sorting in alphabetical order or in ascending / descending order. But almost every day manual sorting is required. For example, we have a certain order of budget items. We need to create a waterfall graph according to the budgetary order of the articles. In this case, you need manual sorting of course. Please, create such feature. To use the exsisting sorts is inconvenient and the graphics are not informative.
