[FIXED] Plotting a chart inside a PyQT GUI

Issue

I would like to plot a chart inside a pyQT GUI. I have already read a lot of tutorials, but those plot the chart in a separeted window. I need it to be ploted in the same window as the other buttons and fields.

In my main.py file, I import the Ui_MainWindow class generated with the QT designer. But I didn't figured out how to plot it inside the MainWindow

Python GUI

Matplotlib canvas class to create figure

class MplCanvas(FigureCanvas):
    def __init__(self):
        self.fig = Figure()
        self.ax = self.fig.add_subplot(111)
        FigureCanvas.__init__(self, self.fig)
        FigureCanvas.setSizePolicy(self, QtWidgets.QSizePolicy.Expanding, QtWidgets.QSizePolicy.Expanding)
        FigureCanvas.updateGeometry(self)

    def atualizar(self):
        global tempoInicio
        tempoInicio = self.campoTempoInicio.dateTime()
        print(tempoInicio.toPyDateTime())

        x=range(0, 10)
        y=range(0, 20, 2)
        self.FigureCanvas.canvas.ax.plot(x, y)
        self.FigureCanvas.canvas.draw()

I've tried as this, but it didn't worked as well (followed a tutorial)

Thank you in advance for reading this.

Solution

After looking into non-relatated tutorial, I've foud this one: https://www.pythonguis.com/tutorials/embed-pyqtgraph-custom-widgets-qt-app/ that teaches how to do what I need.

Don't now why it didn't appear before. But worked!
