termplotlib is a Python library for all your terminal plotting needs. It aims to work like matplotlib.
For line plots, termplotlib relies on gnuplot. With that installed, the code
import termplotlib as tpl import numpy as np x = np.linspace(0, 2 * np.pi, 10) y = np.sin(x) fig = tpl.figure() fig.plot(x, y, label="data", width=50, height=15) fig.show()
produces

import termplotlib as tpl import numpy as np rng = np.random.default_rng(123) sample = rng.standard_normal(size=1000) counts, bin_edges = np.histogram(sample) fig = tpl.figure() fig.hist(counts, bin_edges, orientation="horizontal", force_ascii=False) fig.show()
produces
Horizontal bar charts are covered as well. This
import termplotlib as tpl fig = tpl.figure() fig.barh([3, 10, 5, 2], ["Cats", "Dogs", "Cows", "Geese"], force_ascii=True) fig.show()
produces
Cats [ 3] ************
Dogs [10] ****************************************
Cows [ 5] ********************
Geese [ 2] ********
import termplotlib as tpl import numpy as np rng = np.random.default_rng(123) sample = rng.standard_normal(size=1000) counts, bin_edges = np.histogram(sample, bins=40) fig = tpl.figure() fig.hist(counts, bin_edges, grid=[15, 25], force_ascii=False) fig.show()
produces
Support for tables has moved over to termtables.
termplotlib is available from the Python Package Index, so simply do
pip install termplotlib
to install.
To run the termplotlib unit tests, check out this repository and type
