Re: [Matplotlib-users] Matplotlib & Basemap / What is the Best Graphical Back-end for Raster Data Display (.png) ?

AGG is used for image handling, particularly for handling transforms, scaling, interpolation and such. The AxesImage object that you get from calling imshow() is handled through the AGG library. This is true regardless of the backend being used because it is based in the AxesImage class (and others

Re: [Matplotlib-users] Matplotlib & Basemap / What is the Best Graphical Back-end for Raster Data Display (.png) ?

Matplotlib will not work at all without AGG. Even the AGG-less backends still use AGG for image handling (imshow() and such). We can not guarantee that matplotlib would work with agg 2.5, as that is the GPL'ed version. We develop against a patched 2.4 branch of AGG (which is BSD-licensed), which i

Dear colleagues, I like to receive an advice about the best back-end choice for Matplotlib & Basemap to generate large .png images in a background processing mode. Having issues with the pre-compiled "Agg" package which does not work under my machine architecture. Also not able to recompile th

Re: [Matplotlib-users] matplotlib basemap streamlines plot

Hi, If your flow is actually non-divergent, so that continuous streamlines make sense, you could contour the streamfunction: a decent approximation should be psi = 0.5*( cumsum(u*dy[:,newaxis],axis=1)-cumsum(v*dx[newaxis,:],axis=0)) Of course this won’t work so well if u and v are coarsely space

Hi all, tried to plot a streamline with matplotlib. So far it work's. But my question: Is there a possibility to avoid the gaps in the streamlines (see my picture)? Regards Sappy85 -- View this message in context: http://m

I tested the same plot with a background image in Mercator with same results and I also tested with Mercator covering almost the entire world with the same results. Only a little portion of the background image shows as background although the polygon looks OK in all cases (with maps drawn and wit

Re: [Matplotlib-users] matplotlib/basemap plot geo data on background map

Thanks for your answer. I'm actually looking to plot filled curves whose points are lat/lon points on top of a given background map. The problem experienced is misrepresentation of background map when I insert it using warpimage(), the only function to do this I found so far. Aman Thakral wrote:

Re: [Matplotlib-users] matplotlib/basemap plot geo data on background map

Hi, documentation of mpl_toolkits.basemap.warpimage (http://matplotlib.sourceforge.net/basemap/doc/html/api/basemap_api.html#mpl_toolkits.basemap.Basemap.warpimage) states that it could only be used with a very specific set of images: "Specified image must have pixels covering the whole globe in a

Re: [Matplotlib-users] matplotlib/basemap plot geo data on background map

If you're just looking for points, you can use ax.scatter(). It will plot the points. Also, make sure you set the zorder keyword argument in the scatter. Example: x=range(10) y=range(10) z=range(10,20) ax.scatter(x,y,c=z,zorder=10) Hope this helps, Aman On Fri, Sep 10, 2010 at 1:06 PM, izzybit

Hi Jeff, Do you have in your bags a similar approch but using kriging? For the moment we use R via Rpy to make the computation, but if you know a more pythonic way to do so, I'll appreciate :-) Cordialy Le mardi 10 juin 2008, Jeff Whitaker a écrit : > Jason Li wrote: > > Hi Jeff, > > > > Thanks
