body: <p><a href="https://i.stack.imgur.com/AeBqS.png" rel="nofollow noreferrer">enter image description here</a>
  I'm trying to add a legend in this countplot. I don't know where is the problem? why it's not working. Will any brother help me to solve this problem?</p>
  <pre><code>ax=sns.countplot(x='Tomatoe types', data=df)    
  ax.set_title('Tomatoe types',fontsize = 18, fontweight='bold', color='white')    
  ax.set_xlabel('types', fontsize = 15, color='white')    
  ax.set_ylabel('count', fontsize = 15, color='white')    
  ax.legend(labels = ['Bad', 'Fresh', 'Finest']) 
  for i in ax.patches:    
       ax.text(i.get_x()+i.get_width()/2, i.get_height()+0.75, i.get_height(),  
       horizontalalignment='center',size=14)
  </code></pre>
