I need to create multiple chart under a tabWidget using independent MplWidgets.
Currently, I am creating multiple charts in one single MplWidget. But, in this case whenever I need to move location of MplWidget, I also have to adjust the chart sizes as there are multiple charts in on widget. I am doing it in the following way (multiple charts in one MplWidget):
from PyQt5 import QtWidgets from matplotlib.figure import Figure from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as Canvas import matplotlib.dates as mdates import matplotlib # Ensure using PyQt5 backend matplotlib.use('QT5Agg') # Matplotlib canvas class to create figure class MplCanvas(Canvas): def __init__(self): self.fig = Figure() self.ax1 = self.fig.add_subplot(211) self.ax2 = self.fig.add_subplot(212) self.ax3 = self.ax2.twinx() self.ax1.set_position([0.05, 0.8, 0.65, 0.17]) self.ax2.set_position([0.05, 0.6, 0.65, 0.17]) self.ax3.set_position([0.05, 0.61, 0.65, 0.17]) Canvas.__init__(self, self.fig) Canvas.setSizePolicy(self, QtWidgets.QSizePolicy.Expanding, QtWidgets.QSizePolicy.Expanding) Canvas.updateGeometry(self) # Matplotlib widget class MplWidget(QtWidgets.QWidget): def __init__(self, parent=None): QtWidgets.QWidget.__init__(self, parent) # Inherit from QWidget self.canvas = MplCanvas() # Create canvas object self.vbl = QtWidgets.QVBoxLayout() # Set box for plotting self.vbl.addWidget(self.canvas) self.setLayout(self.vbl)So can you suggest me how can I create multiple independent MplWidgets with only one chart in on MplWidget?

@Piyush I don't understand the problem. Just create several instances of MplWidget each showing one chart.

Could you share some example in python?

@Piyush What examples?
I only saw parts of your code, so I don't know why you're showing several charts in each MplWidget instance. -
