[Chicago-talk] financial charting

[Sean Blanton]

I started out wanting to use Google or Yahoo, and as mentioned in the last
meeting, I ended up using a JQuery-based library, Flot. I use Perl for the
website and to generate the JSON data for the plot. I find the dynamic
highlighting, resizable and interactive web-based plots very attractive. I
use this as a complement to the DataTables plugin (http://datatables.net)
for displaying the data in tables, as the name suggests.

Beware of the JqPlot library, which is also very nice, but does not support
error bars last I checked.

Regards,
Sean
