How to get the data?

[Tough-Stone]

I have been able to get the field names in the dxd file, how can I get the data in each field name?

I assume you are referring to the channel names and channel data. Probably you are looking for the DWChannel.series() method. It returns a Pandas Series containing the data from the channel. For example:

import dwdatareader as dw
with dw.open('myfile.d7d') as f:
    print(f.info)
    data = f['chname1'].series()
    print(data.mean())
