I'm trying to save a large amount of Numpy arrays to a root file using uproot. I've read through the uproot documentation, and as far as I can tell this ability was remove in uproot3. Note I can't save this as a histogram because the order of the data is important (it's a waveform). Does anyone know of a work around, or thing I'm missing to do this?
e.g: I want something like this
'''
import numpy as np
import uproot as up
array = np.random.normal(0,1,1000)
file = up.recreate('./test.root')
file['Tree1'] = array
'''
