pyoscope

Python generic oscilloscope-like plotter

pyoscope.py jlazear 2013-07-17

Generic oscilloscope-like plotting for visualizing data from instruments.

Example:

rt = PyOscope(f='testdata.txt')
rt.data.columns
rt.plot('second', ['first', 'third'], legend=True)

Basic Idea

A generic threaded plotting object that points at a data file and reads it in. The intent is that with these objects, a hardware interface needs to worry only about writing data to a file in a sensible way. Then pyoscope could be invoked completely independently of the interface to handle plotting of the data in a sufficiently flexible way. I want to decouple the plotting of data from the acquisition of data!

Reading in should be done real-time, so file is monitored for updates. Then should either parse header for metadata, e.g. column names, or be passed in a dictionary with this information. Numbers of columns should be automatically determined and referenced in some reasonable way (so measurement-specific names do not need to be used if unwanted or do not exist).

Installation
