      I would like to draw a plotline with nan values.

      zz=dict(_name='zigzag', color='blue', ls='-', _skipnan=True
      

      I have a condition which is activated several times and it sets the value for zz, the problems is that I want to delete the previous zz if this condition is met.

      self.zz[-1] =None
      self.zz[0] = self.data.high[0]
      

      I have already tried this, but an error occurs:

      line 222, in setitem
      self.array[self.idx + ago] = value
      TypeError: must be real number, not NoneType
