How to add "loading..." animation during chart rendering process.
-
Is there a "loading flag" I can access for chart rendering. The idea is that I give the user some indication that "something is happening" when the user changes the dates that my chart is based on, thus causing the chart to rerender. When my from and to dates get far apart, the chart takes a few seconds to do something, and I'd like to show something to the user during this process.
