[Matplotlib-users] Next problem: pixel-to-pixel alpha variation

Hi, folks. OK, I'm trying to set the alpha channel, pixel by pixel, using figimage w/ the data being of the "luminance" type (i.e., an MxN array). The Users Guide indicates that figimage takes an alpha= keyword argument, and it doesn't crash when I pass an array for this value, but subsequentl

[Matplotlib-users] size of the plot

Hi Guys, how can I set the size of a plot window by, let's say, 320 x 180 and make it fix, that is, something like "resize=False". I had a look at the documentation but I couldn't figure out which object and method I have to use for this. Thanks in advance! Bernardo M. Rocha --

Hi all, Michael's solution worked like a charm. Thanks to all for your valuable input! Rgs. >>> Michael Droettboom <[EMAIL PROTECTED]> 09/05/08 7:54 PM >>> You could do something like: def bitget(value, bit_number): return (value & (1 << bit_number)) != 0 which will return True or False fo

[Matplotlib-users] Multiple column legends

Hi! About a year ago, Jouni Seppänen indicated how to put a number of patches in a legend. So far so good. Now, it turns out that I do have quite a lot of patches to throw into this legend, and it would be nice, rather than to have a single column, to have the possibility to arrange these patche

[Matplotlib-users] path and bbox

Hi, wonder if anyone can help me with path and bbox. I have a set of ocean drifter tracks and I want to know if they pass through a particular boxed area. This is straightforward to do but I wanted to try to do it with matplotlib.transforms and matplotlib.path, which look well-suited to this kind

[Matplotlib-users] Re-projecting raster data with Basemap

Hi, I am starting to play with Basemap. I have some raster data in longitude/latitude (WGS-84, EPSG: 4326). I would like to plot it using imshow, and to then plot some country boundaries and so on and so forth. I have studied the plotprecip.py example in Basemap's distribution, but as far as i

Re: [Matplotlib-users] problem with histogram

Yes, I did indeed. Is it sufficient replace the matplotlib directory under the scisoft/ with the one available from the site (0.98.0) to update it? I also noticed that the available Fink package is also the matplotlib-0.91.0. Thanks, Nino Manuel Metz wrote: > Antonino Cucchiara wrote: > >> H

Re: [Matplotlib-users] [SciPy-user] how to plot the result of histogram2d

thanks Johan, I posted to scipy because of histogram2d being in numpy, sorry about that. Now the stupid question, why can't imshow directly parse histogram2d, without the transitory extent object? Anyway, I am happy that there is a simple way as explained below! thanks again, Johann John Hunter
