The functionality here:
The buttons themselves like setting span, start/end dates, go to now, track with time, etc. should all be relatively easy to do in scripting, but the user interaction with the chart itself will need JS to implement which I don't have experience with (yet?). If they can be done though, we could eliminate using the Power Chart altogether which would be exciting!
The other things not specifically mentioned in that post, but that are visible in the screencapture, are:
- the ability to pan the time window back and forth using the mouse to click/drag to swipe through time. And it'd be nice to be able to do this while still in the "x trace" mode.
edit: it looks like your chart does this already, however I'm not sure if the chart data is updating in realtime or if it's just static, but historical trends need the ability to drag back and forth throughout time, outside of the time window that's currently shown. - display the full datetimes for the major gridlines
- zoom window to allow zooming in on a dragged window
