[Matplotlib-users] Contouring a large set of ungridded data

[Jesper L. <jl...@dm...>]

Hi matplotlib users,

I have a long list of ungridded data that I would like to make a contour plot 
of. The data is simply a list of (longitude, latitude, datavalue) with the 
data value belonging the given longitude and latitude. As far as I understand 
contour() only accepts gridded data values.

The solution is probably to interpolate the unstructured data to a regular 
grid and then plot the data. Has anyone tried doing that or know where to 
look for an interpolation/triangulation routine?

Cheers,
Jesper
