[Phpmyadmin-devel] Replacing Highcharts

Quite some, I think. I just checked the code, here's what I found:

Most critical:
- Live update feature of chart data. I didn't see any such feature on the
jqplot examples page. (see main loop for refreshing charts in the monitor:
http://bit.ly/JthtMk)
- Chart value transformation callback that supplies the current and last
value to be displayed. This is needed e.g. for CPU-Linux usage (see
http://bit.ly/MCWSos)

Non critical use cases (lack of these would cut down on features but leave
the charts usable, though some reprogramming might be required):
- Select/Zoom feature with callback
- Tooltips
- Live changing of settings such as titles, refresh rates, labels,
x-axis-extremes
- SVG/PNG or Canvas export
- A .destroy() method so that charts can be loaded and destroyed on demand

Thats all I can think of currently.
