Could you please recommend an interactive charting library that would have ajax scroll/zoom possibility (or at least events tied to x-axis scale) and, optionally, financial analysis features, like SMA/EMA trends or polynomial approximation (since performing these tasks on server-side is nothing but a waste of resources).
I have to display a large set of data (statistical info being collected every 5 minutes for couple of years) and wouldn’t like to re-invent the wheel, but half day of browsing didn’t reveal anything promising.
