Pyqt5, draw a histogram on the control

First, upgrade the control , Details refer to ：
Upgrade the control method
And rename the control
Next, a histogram will be drawn on this control

import sys

from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtChart import (QChart, QChartView, QBarSeries, QBarSet, QBarCategoryAxis, QValueAxis)
from QtCharts import Ui_MainWindow


class Window(QMainWindow, Ui_MainWindow):
    def __init__(self, app):
        super(QMainWindow, self).__init__()
        self.app = app
        self.setup_ui()  #  Rendering the canvas 

    def setup_ui(self):
        self.setupUi(self)  #  call Ui_MainWindow Of setupUi Rendering interface 
        chart = QChart()
        self.setting()
        self.plot_view.setChart(chart)

        chart.addSeries(self.series)
        chart.setTitle(" Parameter index xxx")

        axisY = QValueAxis()
        axisY.applyNiceNumbers()  #  adjustment Y Axis range , Make available to display all data , Easy to watch 
        chart.addAxis(axisY, Qt.AlignLeft)
        self.series.attachAxis(axisY)  #  Data is bound to the coordinate axis 

        self.axis_x = QBarCategoryAxis()  #  Add a category to the axis of the chart 
        daysofweek = ' Algorithm comparison '
        self.axis_x.append(daysofweek)
        chart.addAxis(self.axis_x, Qt.AlignBottom)
        self.series.attachAxis(self.axis_x)

    def setting(self):
        cols = [' Algorithm 1', ' Algorithm 2', ' Algorithm 3']
        data = [53, 24, 85]

        self.series = QBarSeries()  #  Display a series of data as a vertical bar chart grouped by category 
        for i in range(len(cols)):
            setTemp = QBarSet(cols[i])  # QBarSet  Class represents a set of bars in a bar graph 
            temp = data[i]  #  Value of histogram 
            setTemp.append(temp)
            self.series.append(setTemp)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    mywindow = Window(app)
    mywindow.show()
    sys.exit(app.exec_())

This is a simple set of data , You can also draw multiple groups of data
