Plotting to the terminal in python

Question

I'm trying to pick a plotting library to plot data in the terminal, in ASCII format.

In python there are many wrappers for gnuplot but all seems to fall short on the list of requirements:

support python2 and python3
wrap parameters and commands properly instead of being just a thin execution layer
avoid writing down to file system

Also I would like something that is platform indipendent and relying on gnuplot seems to be a deal breaker. This is a nice-to-have, not a strict requirement.

Any suggestion?

I would like to avoid writing my own wrapper and add noise to the ecosystem but the options available seem too rough.

I want to be open to as many possibilities as I can. For now unidimensional and bidimensional data in general, both on a cartesian plane, and as histograms (for unidimensional). In the future I may need graphs but I already saw there are some options for that. — Chobeat, Jun 09 '17 at 11:50

gnuplot doesn't work with python3. I developed my MVP with it and now I need to replace it. — Chobeat, Jun 10 '17 at 09:11

You can try this one: https://github.com/mzechmeister/python/wiki/gplot.py

supports python2/python3/jupyter
supports all commands
option how to transmit data (see parameter tmp: tmpfiles, datablock, etc.)

>>> from gplot import *
>>> gplot.term("dumb")
<gplot.Gplot object at 0x7fd394c17d10>
>>> gplot('sin(x)')
>>>
