Draw a loose graph with matplotlib
Speaking of graphs in python, it is matplotlib, but since it is a bit bad, I think I use seaborn to draw a beautiful graph.
seaborn can easily draw beautiful graphs, but in the presentation materials of the study session We recommend a library that draws handwritten graphs.
How to use
XKCD-stlye seems to be built into matplotlib, so Just write one line at the beginning.
import matplotlib.pyplot as plt
plt.xkcd()
sample
Here are some of the graphs that look like. There are many other samples on the matplotlib glallery page (http://matplotlib.org/xkcd/gallery.html).
Line graph
x = np.arange(-3, 3, 0.1)
y = np.sin(x)
plt.plot(x, y, c='lightskyblue', label='y = sin(x)')
plt.plot([-3, 3], [-1, 1], c='lightcoral', label='y = 1/3x')
plt.legend()
plt.title('Line Plot')
plt.xlabel('x')
plt.ylabel('y')
plt.show()
Normal
Loose fluffy version
Scatter plot
N = 50
x = np.random.rand(N)
y = np.random.rand(N)
area = np.pi * (15 * np.random.rand(N))**2
plt.title('Scatter Plot')
plt.scatter(x, y, s=area, alpha=0.5, c='gold')
plt.show()
Normal
Loose fluffy version
histogram
plt.hist(np.random.randn(1000), color='yellowgreen')
plt.title('Histgram')
plt.show()

Loose fluffy version
pie chart
x = np.array([0.2, 0.4, 0.15, 0.25])
labels = ['Melon', 'Banana', 'Grape', 'Apple']
colors = ['yellowgreen', 'gold', 'lightskyblue', 'lightcoral']
plt.pie(x, autopct='%d%%', labels=labels, colors=colors)
plt.axis('equal')
plt.title('Pie Chart')
plt.show()
Normal
