python (version < 3, I think) uses integer division when given integer values, i.e. 1/1000 = 0, at the expense of giving a less accurate answer than we might expect. If you tried to plot a bunch of values divided by 1000, they may well all be integer 0, and so you wouldn't see any line (it would be at the x-axis). You would need to force python to do floating point division: 1/1000.0 = 0.001; to do this you need to make sure one of the numbers in the division is floating point: the simplest way to do this is 1/1000.0 (or 1/1000. for short). I hope that helps, Angus. > On Mon, Jul 26, 2010 at 1:57 PM, Angus McMorland <amcm...@gmail.com> wrote: >> >> On 26 July 2010 12:47, Waléria Antunes David <waleriantu...@gmail.com> >> wrote: >> > My code like this in django: http://pastebin.com/nzM5jvuc >> >> Are you perhaps suffering from integer division?
