Tried similar, however my plot item ScatterPlotItem does not have 'headLen'
def slot_viewBox_resized(self,viewBox):
length = viewBox.screenGeometry().height()
length -= self.s1.opts['headLen']
self.s1.setStyle(tailLen=length)
self.s1 = pg.ScatterPlotItem(size=2, pen=pg.mkPen(None),
brush=pg.mkBrush(255, 255, 0, 128))
File "lib\_learn\pyqtgraph\02_pyqt.py", line 57, in slot_viewBox_resized
length -= self.s1.opts['headLen']
KeyError: 'headLen'
