Color by y-value¶
Use masked arrays to plot a line with different colors by y-value.
import numpy as np
import matplotlib.pyplot as plt
t = np.arange(0.0, 2.0, 0.01)
s = np.sin(2 * np.pi * t)
upper = 0.77
lower = -0.77
supper = np.ma.masked_where(s < upper, s)
slower = np.ma.masked_where(s > lower, s)
smiddle = np.ma.masked_where((s < lower) | (s > upper), s)
fig, ax = plt.subplots()
ax.plot(t, smiddle, t, slower, t, supper)
plt.show()
