More points in polar plot than expected

Hi there,

telling pyplot

    polar([1,2,3,4],[1,3,4,2], "o")

to my surprise does not give me 4 distinct points but rather some
interpolated points as well. This is highly unexpected, nay, unwanted.
It used to work well in Fedora 8 (don't know which version I ran
there).

Fedora 10
Python 2.5.2
matplotlib 0.98.1

Any ideas?

/W

Works for me on 0.98.3 and SVN HEAD. I get 4 blue dots. Can you send an image showing the output you’re getting?

Yeah. This is a known bug that was fixed since 0.98.1.

Cheers,

Rats! Lets hope the Fedora guys are quick with the updating.

Thanks for ending my head-banging, though.
