uniplot 0.0.2

Lightweight plotting to the terminal. 4x resolution via Unicode.

Uniplot

Simple plotting tool.

When working with production data science code it can be handy to have simple plotting tool that does not rely on graphics dependencies or works only in a Jupyter notebook.

I use this all the time when transforming exploratory code to production Python code. Another use case is having plots as part of your validation tests - that way when something goes wrong, you get not only the error and backtrace but also plots that show you what the problem was.

Features

• Unicode drawing, so 4x the resolution (pixels) of usual ASCII plots
• Super simple API
• Interactive mode (simply pass interactive=True) see demo video
• It's fast: Plotting 1M data points takes 100ms thanks to NumPy magic
• Only one dependency: NumPy (but you have that anyway don't you)

Examples

>>> import math
>>> x = [math.sin(i/20)+i/300 for i in range(600)]
>>> from uniplot.uniplot import plot
>>> plot(x, title="Sine wave")
                          Sine wave
