Exclude range of dates in matplotlib

So I am plotting some 5k time date using matplotlib, using a modified tutorial. I want to remove the ranges between year-01 and year-07 for all years, to make the data more interesting.

This is my code:

import matplotlib.pyplot as plt 

def plotTimes(data):
    x = data["x"]
    y = data["y"]
    fig = plt.figure()
    ax = fig.add_subplot(111)
    ax.grid()

    plt.plot(x,y)
    plt.xlabel('Date')
    plt.ylabel('5k Time')
    plt.title(data['name'])
    plt.show()

• How can I exclude a range of dates from my plot?
• (side question) Is pyplot the best way to use matplotlib?

This is the data:
