How can I get QLineSeries name of graph when mouse horvers in pyqt?

Question

In this picture name of blue line is Week 1 but it displayed as Week 2.

This is my python code.(I used pyqt6.)

for ls_Series in li_Points:
    self.ob_Chart_Viewer.chart.addSeries(ls_Series)
    name = ls_Series.name()
    ls_Series.hovered.connect(lambda point: QToolTip.showText(QCursor.pos(), "%s\nx:%.2f\ny: %.2f" % (name, point.x(), point.y())))
    ls_Series.clicked.connect(ls_Series.hide)
    ls_Series.attachAxis(self.ob_Chart_Viewer.axis_x)
    ls_Series.attachAxis(self.ob_Chart_Viewer.axis_y)

How can I get correct name?

Use:

ls_Series.hovered.connect(
    lambda point, series=ls_Series: QToolTip.showText(
        QCursor.pos(), "%s\nx:%.2f\ny: %.2f" % (series.name(), point.x(), point.y())
    )
)

@bituniverse are you sure? Could you provide an MRE so I can test it. – eyllanesc Oct 08 '21 at 16:36

I found solution. Your code occures error. My solution is to use sender() function. – bituniverse Oct 08 '21 at 17:09
