Re: [Matplotlib-users] Basemap transform_vector for decreasing latitudes

[Jeff Whitaker]

kmanross July 2, 2013 12:42 PM Greetings! Relative newbie here. I'm trying to plot wind vectors using basemap quiver and to fit my ortho projection. This is essentially a hack of Jeff Whitaker's animate.py found at https://github.com/matplotlib/basemap/blob/master/examples/animate.py The data source I'm connecting to, however, has the latitudes in decreasing order, so I get the "lats and lons must be in increasing order!" exception when trying to use the transform_vector method which seems to be required to fit the vectors to the projection. (ugliness occurs when failing to transform) What would be the best way to transform latitudes (to increasing) as needed by transform_vector, while also accounting for the data order of my u and v grids? -kevin. Kevin:  Just flip the data around. lats_flipped = lats[::-1,:] data_flipeed = data[::-1,:] # assuming 2d array shape (nlats,nlons) -Jeff -- View this message in context: http://matplotlib.1069221.n5.nabble.com/Basemap-transform-vector-for-decreasing-latitudes-tp41375.html Sent from the matplotlib - users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
