Nicholas, There's a word for people like you: 'Hero'. The output, in my opinion, looks very nice. Personally, I don't see myself using this for the two-dimensional stuff unless it's because I need to quickly look at something (just like you mention on the glumpy main page), but I think this is a winner for producing 3D plots. GL is a champion when it comes to 3D rendering, a la MayaVI, VTK or Paraview and the current mplot3d toolkit is using all of matplotlib's two dimensional capabilities. I would love to have something like this that mplot3d can hook into to produce publication-quality visualisations in three-dimensional space. I have no experience with the backend side of matplotlib, I just wanted to say thank you for your effort :) -- Damon McDougall http://damon-is-a-geek.com B2.39 Mathematics Institute University of Warwick Coventry West Midlands CV4 7AL United Kingdom ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
