How to write text inside the bar in a horizontal bar graph matplotlib?

My code so far gives me something that looks like this:

I am wanting to write in the bars themselves if possible to get something like this:

Here’s my base code so far:

I’d like to put Disease into the bar

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

x = [u'Rimegepant',u'Rimegepant',u'Zavegepant',u'Zavegepant',u'Troriluzole',u'Troriluzole',u'Troriluzole',u'Verdiperstat',u'Verdiperstat']

y = [4,3,3,3,2,3,3,3,3]

Disease = ['Acute Treatment of Migraine','Preventive Treatment of Migraine','Acute and Preventive Migraine','Lung Inflammation COVID-19',"Alzheimer's Disease", "OCD", "Spinocerebellar Ataxia", "Multiple System Atrophy", "Amyotrophic Lateral Sclerosis"]

fig, ax = plt.subplots()    
width = 0.75 # the width of the bars 
ind = np.arange(len(y))  # the x locations for the groups
ax.barh(ind, y, width, color="green", align='edge')
ax.set_yticks(ind+width/2)
ax.set_yticklabels(x, minor=False)
plt.xticks(np.arange(5),('Pre-clinical','Phase I','Phase II','Phase III', 'Approved'))
plt.margins(0,0.05)
plt.title('BHVN')
plt.ylabel('Drug')

plt.show()

Answer

You can add text to the ax via matplotlib as ax.text().

If you add

for bar, disease in zip(ax.patches, Disease[::-1]):
    ax.text(0.1, bar.get_y()+bar.get_height()/2, disease, color = 'white', ha = 'left', va = 'center') 

just before plt.show() in your code, you’ll get:

Note, I had to reverse your Disease list (using [::-1]) for text to appear the way you have in your image, otherwise Amyotrophic Lateral Sclerosis is on top, and Acute Treatment of Migraine on the bottom.

Function generic form comes in plt.text(x, y, text), so you see I offset x by 0.1 and get y from the bar patch.
