Guides & annotation

Minimal call

import math
xs = [i * 0.2 for i in range(40)]
df = {"x": xs, "y": [math.sin(x) for x in xs]}

c = pt.chart(df, aes(x="x", y="y"))
c.add_line()
c.add_annotate("peak", xy=(1.6, 1.0), xytext=(3.0, 1.2))

Docstring

Text-rendering artists — `text` for data-anchored labels, `annotate`
for a label connected to a point by an arrow.

  c.add_text(aes(x="x", y="y", label="name"))    # columns via aes
  c.add_annotate("peak", xy=(3, 14.7))           # one-off label

Both render glyph paths from the bundled DejaVu Sans so output stays
font-independent.
