Ha yeah - we opened up a port in iptables for this so we don't have to ssh tunnel in to see stats. Obviously, if you're concerned about exposing numbers, you can view via an ssh tunnel instead of opening a port.
Not these guys, but doing realtime viz of signals.
We've switched over to a minimalist canvas renderer--if you don't need interactivity or styling, and instead just "draw me as much as you can as fast as you can, damnit.", we hope it's the way to go.
I've been playing around (http://yield.io) with Flot, which uses canvas and rendering speed seems pretty good, but resizing gets a bit wonky when there are multiple canvas elements on a page.
Yeah, we started with Flotr2...too many graphs on a page (with thousands of datapoints per graph) brings Chrome to its knees, even with auto margins and whatnot turned off.
@angersock That's a good point on the number of points. If I downsampled the yield history to monthly yields, that would probably help the performance.
