5 years ago Hello @FinFighter ,
Thank you for using / trying plotille. The lib was designed to be used in a terminal:
- color output uses ANSI (and extensions) escape sequences, which are interpreted by a terminal as colors. See this wiki article for details. Also it detects, if the script is run in a
ttysession - if not, the escape sequences are not printed. Output would look even more ugly :D (see below) - in the terminal all (most) characters are printed in a grid of equal size, even if the used font uses characters that are not equal width. In most monospace fonts I tested, the braille characters are still wider than the ASCII characters. The terminal forces the characters into the grid. (BTW: the 'whitespace' within the axis are not ordinary space (ASCII 20) characters, but braille characters with no dot set:
\u2800. See _dots.py for details on the handling of each character.)
Since Jupyter notebooks do not have the terminal grid formatting in the output, the braille characters misalign the output with respect to the axis.
Please try the script in the terminal:
import plotille
import numpy as np
X = np.sort(np.random.normal(size=1000))
fig = plotille.Figure()
fig.width = 60
fig.height = 3
fig.height = 30
fig.set_x_limits(min_=-3, max_=3)
fig.set_y_limits(min_=-1, max_=1)
fig.color_mode = 'byte'
fig.plot([-0.5, 1], [-1, 1], lc=25, label='First line')
fig.scatter(X, np.sin(X), lc=100, label='sin')
fig.plot(X, (X+2)**2, lc=200, label='square')
print(fig.show(legend=True))

When plotting many points axes separators tend to become misaligned. Below is an example running a provided example script. This looks like a fantastic tool, would appreciate any help. Thank you.
