simple example using Basemap in a gtk app??

Community matplotlib-users

Hi

Anyone have an example? I found some older examples which no
longer work.

TIA

Mathew

For grins …. The following does not work. I’ve
tried many different variations …

import matplotlib.pyplot as plt

import gtk

from mpl_toolkits.basemap import Basemap

import matplotlib

from matplotlib.figure import Figure

fig=plt.Figure()

ax=fig.add_subplot(111)

m = Basemap(llcrnrlon=1, \

        llcrnrlat=40.6, \

        urcrnrlon=8.8, \

        urcrnrlat = 49.6, \

        projection = 'tmerc', \

        lon_0 = 4.9, \

        lat_0 = 45.1,ax=ax)

from matplotlib.backends.backend_gtkagg import \

                    FigureCanvasGTKAgg as FigureCanvas

canvas = FigureCanvas(fig)

m.drawcoastlines(color=‘gray’)

m.drawcountries(color=‘gray’)

m.fillcontinents(color=‘beige’)

builder = gtk.Builder()

builder.add_from_file(“fluxtool.glade”)

window1=builder.get_object(“window1”)

window1.connect(“destroy”, lambda x:
gtk.main_quit())

vbox=builder.get_object(“vbox1”)

vbox.pack_start(canvas)

window1.show()

gtk.main()

I don’t understand why the following fails.

fig = Figure(figsize=(5,5), dpi=100)

canvas = FigureCanvas(fig)

ax = fig.add_subplot(111)

m = Basemap(resolution=‘c’,projection=‘cyl’,lon_0=0,ax=ax)

m.drawcoastlines(color=‘gray’,ax=ax)

fails with

mpl_toolkits\basemap_init_.pyc in set_axes_limits …

2531 if is_interactive():

2532 figManager = _pylab_helpers.Gcf.get_active()

→ 2533 figManager.canvas.draw()

AttributeError: ‘NoneType’ object has no attribute ‘canvas’

Why isn’t my figure being set as active??

Solved. Sort of. If I run using python it works. It fails if I run using ipython with --pylab.
