Error using FigureCanvasQTAgg in MatplotlibWidget pyqt5
Question: I would like to plot on my GUI with pyqt5 using matplotlib. I have created a
class called MatplotlibWidget which create the figure and canvas of my plot.
But I have a problem to generate my canvas with the FigureCanvasQTAgg function
(which is a matplotlib function).

Here the part of my code which is bugging:

    
    
    import matplotlib.pyplot as plt
    from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg
    from matplotlib.figure import Figure
    
    #Some more code...not relevant
    
    class MatplotlibWidget(QWidget):
        def __init__(self):
            QWidget.__init__(self)
            self.fig = Figure()
            self.canvas = FigureCanvasQTAgg(self.fig) #line 86
            self.axis = self.fig.add_subplot(111)
    
            self.layoutVerticalTest = QVBoxLayout(self)
            self.layoutVerticalTest.addWidget(self.canvas)
    

I have this error :

    
    
    File "/Users/AlexisTuil/Desktop/projet inno/sc_analysis/visualisation.py", line 86, in 
    __init__self.canvas = FigureCanvasQTAgg(self.fig)
    File "/usr/local/lib/python3.5/site packages/matplotlib/backends/backend_qt4agg.py", line 76, in     
    __init__FigureCanvasQT.__init__(self, figure)
    File "/usr/local/lib/python3.5/site-packages/matplotlib/backends/backend_qt4.py", line 71, in
    __init__QtWidgets.QWidget.__init__(self)
    TypeError: __init__() missing 1 required positional argument: 'figure'
    Abort trap: 6
    

I've searched on many forums but i couldn't find out a solution to my problem.
I don't get it why there is a missing "positional argument". Please help me !

I am on MacOS El Capitan with python3.5 64bit. I installed matplotlib with pip
if it can help.

Thanks guys :)


Answer: I finally found out: while using pyqt5 I have to import
matplotlib.backends.backend_q5agg import FigureCanvasQTAgg
