如何隐藏QChart的网格和数值刻度，仅显示折线？

要实现只显示折线，只需对QChart自动生成的坐标轴做隐藏设置即可，以下是修改后的可运行代码：

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QChartView
from PyQt5.QtCharts import QChart, QSplineSeries
from PyQt5.QtGui import QPainter, QPointF

class myChard(QChartView):
    def __init__(self):
        super().__init__()
        self.resize(300, 300)
        self.setRenderHint(QPainter.Antialiasing)
        chart = QChart()
        self.setChart(chart)
        # 不需要标题的话可以删掉下面这句，或者注释隐藏
        chart.setTitle('Simple splinechart example')
        self.getSeries(chart)
        chart.createDefaultAxes()
        chart.legend().setVisible(False)
        
        # 获取X轴并隐藏相关元素
        x_axis = chart.axes()[0]
        x_axis.setVisible(False)  # 隐藏刻度、刻度线、轴线
        x_axis.setGridLineVisible(False)  # 隐藏网格线
        
        # 获取Y轴并隐藏相关元素
        y_axis = chart.axes()[1]
        y_axis.setVisible(False)
        y_axis.setGridLineVisible(False)
    
    def getSeries(self, chart):
        series = QSplineSeries(chart)
        series.append([QPointF(1,1),QPointF(3,1),QPointF(999,1)])
        chart.addSeries(series)

class Window(QWidget):
    def __init__(self):
        super().__init__()
        muChart=myChard()
        layout2 = QVBoxLayout()
        layout2.addWidget(muChart)
        self.setLayout(layout2)
        self.setWindowTitle("Border Layout")

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