Chart Widget edit behavior differs from saved.

Chart plotting 23 sets {dm} for testing. Uses shifting buffer to archive previous data. (Old data shifts back 1 set each update, new data pushed in the front.
In edit mode the old datasets initialize to 0 & new data shifts R>>L as expected.
On exiting the edit mode and loading from "My Watches", the datasets initialize to the new data across all the datasets. ({dm} == 34 results in 34 across the chart) Then the behavior is as expected with new data replacing old shifting R>>L as expected.
