I want to use matplotlib as a component of a larger, event-driven GTK
app. That means pylab.show is (I think) not the way to go, as it
starts up its own event loop which doesn't return. I've tried to clear
and plot in my event handler, but my plot is never displayed.
My initialization code looks like this:
matplotlib.use("GtkAgg")
....
self.figure = matplotlib.figure.Figure()
self.plot = self.figure.add_subplot(111)
self.plot.set_axisbelow(True)
self.figure.tight_layout()
My event handler computes a new set of points (about a dozen x/y
pairs) and plots them:
points = ... generate a list of (x, y) tuples ...
print points
self.plot.clear()
self.plot.plot([x for x, y in points], [y for x, y in points])
Every time my event handler is called, it prints the points (I see
them in my xterm), but the plot is never drawn.
I looked at this example:
http://matplotlib.org/examples/user_interfaces/embedding_in_gtk2.html
but it does something with a key press handler that seems very
artificial, and not at all like how my application will interact with
its environment. Can someone point me to the correct spot in the
documentation or some examples that don't require the user to type at
the application?
Thanks,
Skip
