We will create two lines, i.e., line1 and line2. After that, we will pop the second line and will remove it.

Steps

Create lists for line1 and line2.
Plot line1 and line 2 using plot() method, line 2 with style =’dashed’.
Set or retrieve auto-scaling margins(0.2).
Pop line 2, and remove it using remove() method.
The final figure will have only one line, so use plt.show() method.

Example

import matplotlib.pyplot as plt

line1 = [2, 4, 8]
line2 = [3, 6, 12]

plt.plot(line1)
line_2 = plt.plot(line2, linestyle='dashed')
plt.margins(0.2)
plt.title("With extra lines")
plt.show()

plt.plot(line1)
l = line_2.pop(0)
l.remove()
plt.margins(0.2)
plt.title("Removed extra lines")

plt.show()
