Re: [Matplotlib-users] ocean profile
I'd love to see it included to -- I believe the problem is finding a good code that is BSD compatible. Yes. Some examples on plotting data using spatial interpolation would be very nice. One with the delauny package: see below at: http://scipy.org/scipy/scikits/ And one with griddata: http://code.google.com/p/griddata-python/ We could use the accepted data sets from http://www.itc.nl/personal/rossiter/teach/lecnotes.html#l6 I have tested the griddata package but didn't reach very far due to other task to be accomplished earlier.

I just talked with Jeff Whitaker who wrote the griddata functionality on top of NCAR's natgrid (GPL), and he expressed a willingness to port his code to use Robert's code, which we could include in mpl. Robert, what is the reason this hasn't gone into scipy proper, and do you see any problems with us folding it into mpl for use by griddata?

To draw a contour plot of that data, you need to interpolate it onto a regular grid. Here is wiki page about that: http://www.scipy.org/Cookbook/Matplotlib/Gridding_irregularly_spaced_data In there, is says that MPL does not have this functionality built in -- is that still true?
