How to create a 2d line chart using matplotlib?
1.Import some python libraries
import numpy as np import matplotlib.pyplot as plt
2.Prepare sine(x) data
x = np.linspace(0, 2 * np.pi, 20) y = np.sin(x)
where x will be displayed on x axis, y will be displayed on y axis
3.Create a 2d line chart
plt.plot(x, y, c='#ff6600')
plt.title('sin(x)')
plt.xlabel('x axis')
plt.ylabel('y axis')where parameter c will set the line color.
4.Show 2d line chart
plt.show()
