Python 3.x Python3使用Glade在GTK3内嵌入Matplotlib图

我正在使用

Python3

和

Glade

，我需要在动态变化的

GtkBox

中嵌入一个绘图，我遵循本教程：

只是好像什么都没发生，我在执行过程中出错了：

main.py:78:警告：尝试删除源ID 39时未找到它 Gtk.main（）

这是代码中关于绘图的部分：

print("plot")
figure = Figure(figsize=(5,5), dpi=100)
ax = figure.add_subplot(111)

N = 20
theta = linspace(0.0, 2 * pi, N, endpoint=False)
radii = 10 * random.rand(N)
width = pi / 4 * random.rand(N)

bars = ax.bar(theta, radii, width=width, bottom=0.0)

for r, bar in zip(radii, bars):
    bar.set_facecolor(cm.jet(r / 10.))
    bar.set_alpha(0.5)
print("pre-plot")
ax.plot()
print("post-plot")

canvas = FigureCanvas(figure)  # a Gtk.DrawingArea
containerbox.remove(schermata1) #schermata1= GTKBOX
sw.add_with_viewport(canvas) #sw= GtkScrolledWindow
containerbox.add(schermata2) #schermata2= GtkBox whit sw inside

我的进口：

from gi.repository import Gtk
from numpy import arange, pi, random, linspace

from matplotlib.figure import Figure
from matplotlib.axes import Subplot
from numpy import arange, sin, pi
import matplotlib.cm as cm
from matplotlib.backends.backend_gtk3cairo import FigureCanvasGTK3Cairo as FigureCanvas
