Templates

Single plot

fig, ax =  plt.subplots(figsize=(18, 5))

Multiple Plots

One row, two columns:

fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(18, 5))

Chart Types

Line

ax.plot(xs, ys)

Vertical Line

ax.plot(x, color='red')

Properties

Dimensions

Do on creation, via figsize:

fig, ax =  plt.subplots(figsize=(18, 5))

Width 18 and height 5 are assumed to be inches.

Title

ax.set_title('My title')
