Sorting a Lumira Bar or Line Chart by a Date Dimension

Created Lumira Bar chart with a date dimension on the X-axis. Looked great with the date sorted oldest to newest, but the user wants the date sorted newest to oldest. Used the "Sorted by Dimensions" icon to change the sort. It changed the sort to the other dimension. Clicked it again and it sorted the the other dimension descending. Third time the sort icon changed the date dimension back to the starting sort order. Never did change the date to newest to oldest. Can anyone suggest a way to sort the date dimension to newest to oldest in a chart?
