That's behind http://speed.pypy.org/ and http://speed.twistedmatrix.com/. It's using one of the Javascript graph frameworks. jqplot [1] to be precise.

It's not just for x/y charts. All Linux distributions I know have it. Since it's not written in only Python for performance reasons to install it by hand may cause some dependency hunting.

Re: How to draw line charts in Django?
One other approach is that you can send the data to matplotlib (which is python) and use that to create a .png which you then serve--it depends on what your needs are.

Can you share me sample? I've recently done a project that uses Ajax, jQuery, and Flot to do some charting/graphing. It's not incredibly well-commented, but take a look and see if it helps: https://github.com/jacobian/django-dev-dashboard Jacob -- You received this message because you are subscribed to the Google Groups "Django users" group.
