Looking for jQuery charting options
I am working on a project right now that calls for an interactive visualization of about 300 data points. They are being plotted along two axes, similar to a scatter chart. In reality each point belongs to two different series (15 in one direction, close to 150 in the other), and at times the linkages in each of those directions will be exposed.
My question, then, is this – what plugins or options should I investigate? I’ve looked at Flot, RGraph (briefly) and jqPlot over the last few days; each of them has nice points, but each falls a bit short of my goals.
A few of the main points I’m looking for are:
– the ability to turn layers off and on; Flot does this, I haven’t seen anything in jqPlot.
– custom tooltips, with values not from that point’s X-Y coordinates. It seemed like jqPlot could do this, but really it seems that it accepts non-numeric axes labels? Also, these tooltips cannot be present at all times; doing so would be highly problematic.
Any tips you have would be great.
