Description of problem: When editing the portlets of the dashboard the contents of the dashboard graphs need refreshing. How reproducible: Always Steps to Reproduce: 1. Goto Dashboard 2. Click Edit Mode 3. Notice that graphs look empty until a minute later once an auto refresh takes place.
Proper refreshing of the graphs is displayed now when changing dashboard edit modes from view <--> edit. This is because chart(d3) draw is two stage as opposed to all other portlets are single stage drawing. committed to master: d81ef0a
