billionaire_matplotlib.py

from matplotlib import pyplot as plt
plt.style.use("fivethirtyeight")

COLORS = ['#456789', '#894567', '#678945', '#3B3D4B', '#FF8181']

# Create data
x4 = ['$50K (Median Salary)', '$1 Million', '$1 Billion']
y4 = [50000, 1000000, 1000000000]

# Create a figure and axis
fig4, ax4 = plt.subplots(figsize=(50, 10))
ax4.set_title('How much money is a billion dollars?', fontsize=60)

# Plot the data 
ax4.barh(x4, y4, color=COLORS[:2])

# Remove x-axis ticks
ax4.get_xaxis().set_ticks([])

# Adjust font size for a few different attritubtes
for item in ([ax4.title, ax4.xaxis.label, ax4.yaxis.label] +
             ax4.get_xticklabels() + ax4.get_yticklabels()):
    item.set_fontsize(25)
