[Matplotlib-users] Patch + facecolors
Dear matplotlib users, I would like to know if there is in matplotlib the following Matlab function: *p=patch(x(TRI'),y(TRI'),u(TRI'),u(TRI'));* *set(p,'FaceColor','interp','EdgeColor','black');* where TRI are the coordinate of many non regular rectangles. I would like to do that because I have a not-structured grid whose elements are irregular rectangles. I would like to plot a 3D surface of the values on each points of the grid.

Re: [Matplotlib-users] Pyplot contour plot - clabel padding
I meant plt.xlim and plt.ylim. But its hard to tell what the problem is w/o some sample code.

Re: [Matplotlib-users] Pyplot contour plot - clabel padding
Hi Jody,
i have posted the code. Here again:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
import pygrib
filename = file.grib2
grbs = pygrib.open('/data/' + filename)
grb= grbs[2]
data = grb.values
datac = data*0.01
lats, lons = grb.latlons()
fig = plt.figure()
m = Basemap(projection='stere',lon_0=5,lat_0=90.0,\
llcrnrlon=-25.0,urcrnrlon=60.0,llcrnrlat=30.0,urcrnrlat=60.0,resolution='l')
x, y = m(lons, lats)
levs = range(940,1065,5)
S1=plt.contour(x,y,datac,levs,linewidths=0.5,colors='b')
plt.clabel(S1,inline=1,inline_spacing=0,fontsize=8,fmt='%1.0f',colors='b')
m.drawmapboundary(fill_color='w')
m.drawcoastlines(linewidth=0.2)
plt.savefig('test.png', bbox_inches='tight',pad_inches=0.05, dpi=100)

Re: [Matplotlib-users] Patch + facecolors
I am a bit confused. Your variable is TRI, but you keep saying
rectangles. You are also referring to unstructured rectangles, which makes
zero sense to me. Do you mean triangles?
If you, matplotlib has the tri- family of functions and a whole module
devoted to triangulation-related tasks:
http://matplotlib.org/api/tri_api.html
http://matplotlib.org/examples/pylab_examples/tricontour_demo.html
Even the mplot3d toolkit has (limited) support:
http://matplotlib.org/examples/mplot3d/trisurf3d_demo.html
I hope that helps!

Re: [Matplotlib-users] Key events using nbagg backend
Woops! You're absolutely right! I was completely confused! I mixed up the new nbagg backend with the way ipython notebooks used to display matplotlib figures. The nbagg backend is indeed interactive (and I have no idea why key press callbacks aren't supported, then). This is what happens when I reply to e-mail without putting much thought into it. Thanks! -Joe On Thu, Dec 4, 2014 at 8:58 PM, Brendan Barnwell brenb...@brenbarn.net wrote: On 2014-12-04 15:40, Joe Kington wrote: Nbagg is non-interactive, similar to Agg. No events other than draw events are supported, as far as I know. If that's the case, the release notes should probably make that clear. Right now at http://matplotlib.org/users/whats_new.html#the-nbagg-backend it says: Phil Elson added a new backend, named “nbagg”, which enables interactive figures in a live IPython notebook session. The word interactive certainly could lead people to believe that the backend is, in fact, interactive. -- Brendan Barnwell Do not follow where the path may lead.
