Python Bar Chart X axis re-naming matplotlib [duplicate]

my question is simply how would I change the X-axisOUTCOME OF CODE FOR BAR CHART

from the numbers (Ex. 17, 1, 2, 4) to the PET names (Ex. Horse, Dog, etc). Code Below

I'm new to stack overflow but here is an image of the code. I'll eventually figure out how to use it.

Here is my code.

Code:

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

h2 = pd.read_csv("hw_2_data.csv")

## create grouped dataframe
h2Grouped = h2.groupby('Pet').count()
##h2Grouped

##recreate serverity variable
h2Grouped['Pet'] = h2Grouped.index
## rename the variables
h2Grouped.columns = ['Count', 'Pet', 'Ice Cream', '#of letters', 'Favorite TA', 'Minutes to Hometown']

#matplot
%matplotlib inline

##bar
bar1 = h2Grouped.plot.bar(x = 'Pet', y = 'Count', title = 'Pet Bar Chart')
bar1.set_xlabel('Pet')

##get rid of text output
t = bar1.set_ylabel('Count')
