Time series resampling #140

Closed twiechert closed 5 years ago

twiechert commented 6 years ago

According to the list of available transformation operations, Chronix does currently not support resampling (or am I missing something?).

Since I need this feature urgently, I would implement it myself. Is there anything important to consider?

I would implement it as a transformation operation that expects the new frequency size, similar to the MovingAverage transformation. Then I would apply the mean to obtain one value per interval, what might be configurable in an improved version.

Hi, currently there is no function to resample time series (sadly). But i would appreciate it, if you implement such a function. It should be straight forward.

I have create a branch called chronix-resample-function that already provides a skeleton.

It would be nice to talk about the details / questions in gitter.
