>> Is another interactive backend supported for matplotlib? Jochen> I am happily using GTKagg with MacPort's python25 on Leopard. I tried that but get this traceback: % /opt/local/bin/python2.5 Python 2.5.2 (r252:60911, Mar 5 2008, 22:37:23) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from pylab import * Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/opt/local/lib/python2.5/site-packages/pylab.py", line 1, in <module> from matplotlib.pylab import * File "/opt/local/lib/python2.5/site-packages/matplotlib/pylab.py", line 292, in <module> from matplotlib.pyplot import * File "/opt/local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 37, in <module> new_figure_manager, draw_if_interactive, show = pylab_setup() File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/__init__.py", line 24, in pylab_setup globals(),locals(),[backend_name]) File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_gtkagg.py", line 10, in <module> from matplotlib.backends.backend_gtk import gtk, FigureManagerGTK, FigureCanvasGTK,\ File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_gtk.py", line 21, in <module> from matplotlib.backends.backend_gdk import RendererGDK, FigureCanvasGDK File "/opt/local/lib/python2.5/site-packages/matplotlib/backends/backend_gdk.py", line 29, in <module> from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array ImportError: No module named _backend_gdk Given that py25-matplotlib didn't depend on py25-gtk, my guess is that it wasn't built with Gtk support. How do I do that? Thx, -- Skip Montanaro - skip@pobox.com - http://www.webfast.com/~skip/
