How to create a dynamic line graph like Google Finance has?

Question

I'm looking to create a dynamic zoomable line graph for a web page I'm doing.

I was told to "make it like Google's one" (though by a sales guy who in turn is parroting the client, so he's aiming high. They'll all come right back down to earth once I tell him how much it'll cost!)

Can somebody recommend where to start with this? Are there any available jQuery plugins out there? Or other means of producing something similar?

Answer 1

You can try google charting APIs like Wyatt noted, however, do keep in mind that google pulls data to its severs, and if your client has any privacy hassles, maybe thats not the solution to go for.

I would recommend these - jqPlot - Good looks, MIT / GPL licence, interactive, http://www.jqplot.com/

flot - Good looks, Open source, interactive, http://code.google.com/p/flot/

Highcharts - Multiple licenses (might have to pay) http://www.highcharts.com/

Lots of other options, but these are all javascript based :)

Answer 2

You can use the same toys google is using for starters.
