pyqt6 使用qcharts绘制曲线示例

非常感谢您的提问。这是一个很好的问题。这里提供一个简单的示例，用于使用PyQt6和QCharts绘制曲线。

import sys
from PyQt6.QtCore import Qt
from PyQt6.QtGui import *
from PyQt6.QtWidgets import QApplication, QMainWindow, QChartView, QValueAxis, QLineSeries, QVBoxLayout, QHBoxLayout, QWidget
from PyQt6.QtCharts import QtCharts

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("PyQt6 QChart Example")

        # create chart and set general options
        self.chart = QtCharts.QChart()
        self.chart.setTitle("Chart Title")
        self.chart.setAnimationOptions(QtCharts.QChart.SeriesAnimations)

        # create xaxis and set general options
        axisX = QtCharts.QValueAxis()
        axisX.setLabelFormat("%d")
        axisX.setTitleText("X Axis Title")
        axisX.setTickCount(10)
        axisX.setRange(0, 10)

        # create yaxis and set general options
        axisY = QtCharts.QValueAxis()
        axisY.setLabelFormat("%.2f")
        axisY.setTitleText("Y Axis Title")
        axisY.setRange(0, 100)

        # create line series and add it to chart
        series = QtCharts.QLineSeries()
        series.setName("Line Series")

        # add data to line series
        series.append(0, 10)
        series.append(1, 20)
        series.append(2, 30)
        series.append(3, 40)
        series.append(4, 50)
        series.append(5, 60)
        series.append(6, 70)
        series.append(7, 80)
        series.append(8, 90)
        series.append(9, 100)

        # add series to chart
        self.chart.addSeries(series)

        # set xaxis and yaxis to chart
        self.chart.setAxisX(axisX, series)
        self.chart.setAxisY(axisY, series)

        # create vertical layout and chart view
        layout = QVBoxLayout()
        chartView = QChartView(self.chart)
        chartView.setRenderHint(QPainter.Antialiasing)

        # add chart view to layout
        layout.addWidget(chartView)

        # create horizontal layout and add widgets
        hbox = QHBoxLayout()
        widget = QWidget()
        widget.setLayout(hbox)

        # add layout to horizontal layout
        hbox.addLayout(layout)

        # set central widget of main window
        self.setCentralWidget(widget)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec())

这个示例创建了一个带有标题和x，y轴标签的图表。它使用QValueAxis来设置X和Y轴，并使用QLineSeries来绘制曲线。数据通过调用series.append()方法添加到曲线上。最后，QChartView用于绘制图表，并将其添加到主窗口中。

希望这个示例可以帮助你入门PyQt6和QCharts。如果您有任何其他问题，请随时问我。
