Description:
 Simple Plotting Example
First we import the modules matplotlib for plotting and numpy for numerical array manipulation
Step1:  Next we set the variable xs to be an array of 100 equally spaced points in the interval [-1,1]
Step2:  Now we set the array ys to be the elementwise square of xs
Step3:  Now we plot the result using matplotlib
<ASSISTANT_TASK:>
Python Code:
from matplotlib import pyplot as plt
import numpy as np
Explanation: Simple Plotting Example
First we import the modules matplotlib for plotting and numpy for numerical array manipulation:
End of explanation
xs = np.linspace(-2, 2, num=100)
print(xs)
Explanation: Next we set the variable xs to be an array of 100 equally spaced points in the interval [-1,1]:
End of explanation
ys = xs*xs
print(ys)
Explanation: Now we set the array ys to be the elementwise square of xs:
End of explanation
plt.plot(xs, ys)
plt.xlabel('x')
plt.ylabel('y')
plt.title('plot of y = x**2')
plt.show()
Explanation: Now we plot the result using matplotlib:
