Numpy Array to LineBuffer

[Developing Coder]

I'm doing some math in an indicator and in the process LineBuffer is converted into a Numpy ndarray. Is it possible to convert back?

Example:

log_hl = np.log(self.datas[0].high / self.datas[0].low)

You have gotten a standard Python list from from of the lines and used to create a ndarray.

In any case there is no need to do neither a nor b. Use ApplyN and use the function of your choosing (apparently log) - Docs - Indicator Reference
