RocketLogger Python Support

This package provides RocketLogger data file handling support, basic data processing and plotting of the data.

Dependencies:

• Python 3: version 3.5-3.7

• NumPy: version 1.13-1.17

Optional dependencies: * Matplotlib: for plotting data overview * pandas: for DataFrame export

Data Import

To import a RocketLogger data (.rld) file, simply do:

>>> from rocketlogger.data import RocketLoggerData
>>> rld = RocketLoggerData('data.rld')

To merge channels with auto-ranging, i.e. the current channels:

>>> rld.merge_channels()

To get the loaded channel data (by name) and corresponding timestamps:

>>> d = rld.get_data(['V1', 'I1'])
>>> t = rld.get_time()

A list of the channels existing in the loaded file is provided by:

>>> ch = rld.get_channel_names()

To plot a preview of the data (requires Matplotlib):

>>> p = rld.plot()

You can also plot the (merged) file data a single command, e.g. for preview:

>>> p = RocketLoggerData('data.rld').merge_channels().plot()

For analysis using pandas, the use the following shortcut to get a time indexed dataframe (requires pandas):

>>> df = rld.get_dataframe()

RocketLogger Device Calibration

The :RocketLoggerCalibration: class provides the necessary support for generating device calibration files. See the calibration section in the package documentation <https://rocketlogger.ethz.ch/python/> and the RocketLogger wiki at <https://rocketlogger.ethz.ch/wiki/> for more details on the calibration procedure.
