 [Matplotlib-users] draw lines in basemap From: David Craig - 2012-02-29 12:28:12 ```Hi, I'm trying to produce a map with 12 locations marked on it and straight lines plotted between each point and all other points on the map. I have the map with the locations ok but am having trouble getting the lines. My code is below anyone know how to do this??

You can plot the markers and the lines at the same time like so: from mpl_toolkits.basemap import Basemap import matplotlib.pyplot as plt import matplotlib.lines as lines import numpy as np m = Basemap(llcrnrlon=-11.5,llcrnrlat=51.0,urcrnrlon=-4.5,urcrnrlat=56.0, resolution='i',projection='cass',lon_0=-4.36,lat_0=54.7) lats = [53.5519317,53.8758499, 54.2894659, 55.2333142, 54.9846137,54.7064869, 51.5296651, 51.5536226, 51.7653115, 52.1625237, 52.5809163, 52.9393892] lons = [-9.9413447, -9.9621948, -8.9583439, -7.6770179, -8.3771698, -8.7406732, -8.9529546, -9.7907148, -10.1531573, -10.4099873, -9.8456417, -9.4344939] m.plot(x, y, 'D-', markersize=10, linewidth=2, color='k', markerfacecolor='b') m.drawcoastlines() plt.show() Hope that helps, -paul On Wed, Feb 29, 2012 at 4:27 AM, David Craig wrote: > Hi, > I'm trying to produce a map with 12 locations marked on it and straight > lines plotted between each point and all other points on the map.
