当鼠标悬停在pyqt中时，如何获取图形的QLineSeries名称？

from PyQt5.QtChart import QChart, QLineSeries

chart = QChart()

series = QLineSeries()
chart.addSeries(series)

chart.setTitle("Chart Title")
chart.setAxisX(QValueAxis(), series)
chart.setAxisY(QValueAxis(), series)

chart_view = QChartView(chart)

def handle_hover(event):
    point = chart.mapToValue(event.pos())
    for series in chart.series():
        if series.hovered(point):
            print("QLineSeries名称:", series.name())

chart_view.setMouseTracking(True)
chart_view.mouseMoveEvent = handle_hover
