点击左侧的CTA回测 app的时候，出现报错 Can't add an axis to multiple plots. Shared axes can be achieved with multiple AxisItem instances and set[X/Y]Link，
麻烦各位大佬帮忙看看这个错有遇到过吗， 版本是2.1.8

完整的错误堆栈：

Traceback (most recent call last):

plot = pg.PlotItem(axisItems={'bottom': self._x_axis})

遇到这个错误：

RuntimeError: Can't add an axis to multiple plots. Shared axes can be achieved with multiple AxisItem instances and set[X/Y]Link.

如果不降级 pyqtgraph，有其他办法解决吗？多谢
