How do I sort the Barcode Chart?

I have a query that returns the stories that do not have requirements. Within the Result Layout, I have set the Sort Order to "Planned For."

Within the query window the data returns in the correct sort order.

If i use the Work Items Widget and attach it to the query specified above, the data returns in the correct order.

If I use the Work Items Statistics Widget and attach it to the query specified above, the data returns in an incorrect order. it returns in the order of greatest number of records to the minimum. By example:

Sprint 1 - 5
Sprint 2 - 3
Sprint 3 - 4
Sprint 4 - 1

This is the order for the Work Items Widget, the order the graph shows is:

Sprint 1 - 5
Sprint 3 - 4
Sprint 2 - 3
Sprint 4 - 1

I tried to use the Group Filters box to do the sorting with no result.

I noticed that most graphs sort by the y-value access rather then the x-axis. How do I change this?

Thanks
