python module for interactive web charts

[Moosebumps]

Is there anything that is made to generate web pages which have charts
similar to the yahoo finance stock charts? Not looking to graph stocks
specifically, but anything. I like how you can zoom on each axis, and maybe
click to see numerical values and such.

If there isn't anything in Python, what do people typically use for that
kind of stuff, or is it all hand-rolled?

thanks,
MB

matplotlib is a 2D plotting library that supports a number of plot
types - http://matplotlib.sourceforge.net/screenshots.html. The
library can generate plots either to GUIs or just generate images if
you want to use it in a web application server. See this link
http://matplotlib.sourceforge.net/faq.html#APPSERVER for more
information about using matplotlib in a web server. There are
interactive navigation tools for panning and zooming, etc.

The next release 0.53 due out early next week will have a lot of
support for making date plots, using python datetimes, mx.Datetime, or
other, with a hodge podge of minor and major date tick locators and
formatters. There is also a financial module in the works which will
be finished soon for candlestick plots and the like.

If you're interested in getting announcements when these features are
ready, you may want to join the mailing list
http://lists.sourceforge.net/mailman/listinfo/matplotlib-users.

Cheers,

Thanks, that looks great -- just what I'm looking for! As a note, it's nice
that all the figures are anti-aliased -- even a lot of commercial packages
that I looked at don't have that.
