Bug summary
My program is ran correctly with matplotlib2.2.2 ,but it quits unnormally without reporting error when matplotlib is upgrade to 3.0.
Code for reproduction
import matplotlib
matplotlib.use('TkAgg')
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure
def createWidgets(self):
fig = Figure(figsize=(8, 6), dpi=100)
self.ax_vp = fig.add_subplot(231)
self.lines_vp, = self.ax_vp.plot([], [])
self.ax_ip = fig.add_subplot(232)
self.lines_ip, = self.ax_ip.plot([], [])
self.ax_pp = fig.add_subplot(233)
self.lines_pp, = self.ax_pp.plot([], [])
self.ax_vb = fig.add_subplot(234)
self.lines_vb, = self.ax_vb.plot([], [])
self.ax_ib = fig.add_subplot(235)
self.lines_ib, = self.ax_ib.plot([], [])
self.ax_pwm = fig.add_subplot(236)
self.lines_pwm, = self.ax_pwm.plot([], [])
self.canvas = FigureCanvasTkAgg(fig, master=self)
self.canvas.get_tk_widget().pack(side=tk.TOP, fill=tk.BOTH, expand=1)
self.canvas._tkcanvas.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
def draw(self):
self.update_draw(self.lines_vp,self.ax_vp,self.datas['Vpv'])
self.update_draw(self.lines_ip,self.ax_ip,self.datas['Ipv'])
self.update_draw(self.lines_pp,self.ax_pp,self.datas['Ppv'])
self.update_draw(self.lines_vb,self.ax_vb,self.datas['Vboost'])
self.update_draw(self.lines_ib,self.ax_ib,self.datas['Iboost'])
self.update_draw(self.lines_pwm,self.ax_pwm,self.datas['PWM'])
self.canvas.draw()Actual outcome
#this program quit without any outcome
# If applicable, paste the console output here
