Any way to get dashboard charts to "crawl" rather than "refresh?"

[mikeely]

I've got this useful-looking area chart on a dashboard and used XML to cause it to refresh every thirty seconds. What I'd really prefer for it to do would be to build from right to left without the whole thing blanking while the report runs. Is this doable?

Seems to me that you'd want to change the chart to use a real-time search, rather than a historical search. Starting with 4.3 (and actually in 4.2.3+ if you want to change the default settings in limits.conf), you can have a real-time search backfill with historical data (e.g., if you start it up for a 1-hour window, it will fill in the past 1 hour, then start updating going forward.)
