Overview
import matplotlib.pyplot as plt
plt.style.use('seaborn-v0_8-whitegrid')
x = [1, 2, 3]
y = [10, 23, 4]
x2 = [1, 2, 3]
y2 = [11, 25, 6]
fig, ax = plt.subplots()
fig.suptitle('Something')
ax.set_xlabel('length')
ax.set_ylabel('height')
ax.plot(x, y, 'g', x2, y2, 'b', lw=0.5)
plt.show() # not needed in Jupyter
Difference between Plot and Scatter
Input Data
plot([x], y, [fmt], ...)
where fmt is a format string.
The coordinates of the points or line nodes are given by x, y.
Multiple Series
If multiple pairs of x/y arguments are provided, multiple lines are plotted:
def plot([x], y, [fmt], [x2], y2, [fmt2], ..., **kwargs)
Style
To set globally, see:
Format String
Color "r" for red.
Line Width, Color, Style, Marker
ax.plot(x, y, linewidth=0.5)
ax.plot(x, y, lw=0.5)
ax.plot(x, y, color='green', marker='o', linestyle='dashed', linewidth=2, markersize=12)
Multiple Series Formatting
# first line green, second blue
ax.plot(x, y, 'g', x2, y2, 'b', lw=0.5)

Labels
ax.set_xlabel('length')
ax.set_ylabel('height')
