python读取excel文件并用pyqt5进行可视化分析

可以使用Pandas库来读取Excel文件，并使用PyQt5进行可视化分析。以下是一个简单的示例代码：

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QTableWidget, QTableWidgetItem, QChartView, QChart
from PyQt5.QtGui import QStandardItemModel, QStandardItem
from PyQt5.QtChart import QBarSet, QBarSeries, QBarCategoryAxis, QValueAxis
import pandas as pd

class ExcelAnalyzer(QMainWindow):
    def __init__(self, filename):
        super().__init__()
        self.filename = filename
        self.tableWidget = QTableWidget()
        self.chartView = QChartView()
        self.setCentralWidget(self.chartView)
        self.load_file()

    def load_file(self):
        df = pd.read_excel(self.filename)

        # create a bar chart
        chart = QChart()
        chart.setTitle('Sales by Product')
        chart.setAnimationOptions(QChart.SeriesAnimations)

        # add data to the chart
        for col in df.columns[1:]:
            sales = df[col].sum()
            set = QBarSet(col)
            set.append(sales)
            series = QBarSeries()
            series.append(set)
            chart.addSeries(series)

        # set up the axes for the chart
        axisX = QBarCategoryAxis()
        axisX.append(df.columns[0])
        chart.addAxis(axisX, self.chartView.ChartTypeCartesian, QChart.Bottom)
        axisY = QValueAxis()
        axisY.setRange(0, df.iloc[:,1:].values.max())
        chart.addAxis(axisY, self.chartView.ChartTypeCartesian, QChart.Left)
        for series in chart.series():
            series.attachAxis(axisX)
            series.attachAxis(axisY)

        self.chartView.setChart(chart)
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    analyzer = ExcelAnalyzer('example.xlsx')
    sys.exit(app.exec_())

这个代码将会在窗口中展示Excel表格的内容并生成一个柱状图，用于分析Excel表格中的数据。你可以根据需要修改代码以适应你的具体需求。
