在pyqt5中动态更改数据划线

from PyQt5.QtCore import QTimer
from PyQt5.QtCharts import QLineSeries, QChart, QChartView
from PyQt5.QtWidgets import QApplication, QMainWindow

app = QApplication([])

# 创建图表和系列
series = QLineSeries()
chart = QChart()
chart.addSeries(series)
chart.createDefaultAxes()

# 创建视图并设置图表
view = QChartView(chart)
view.setRenderHint(QPainter.Antialiasing)

# 设置窗口
window = QMainWindow()
window.setCentralWidget(view)
window.show()

# 模拟数据更新
def update_data():
    series.append(series.count() + 1, series.at(series.count() - 1).y() + 1 if series.count() > 0 else 0)
    chart.axisX().setRange(0, series.count())
    chart.axisY().setRange(0, max(10, series.at(series.count() - 1).y() + 1))

timer = QTimer()
timer.timeout.connect(update_data)
timer.start(1000)  # 每秒更新一次

app.exec_()
