title: Seaborn pairplot ValueError: max must be larger than min in range parameter
body: <p>I am getting this error while plotting pairplot using seaborn library in Python. With reference to the previous questions asked on the same topic, I cleaned my data and verified if I have any null value,</p>
  
  <pre><code>train_data.isnull().values.any()
  Out[91]: False
  
  import seaborn as sns
  sns.pairplot(train_data)
  </code></pre>
  
  <p>I am still getting this Value Error for a seaborn plot. I am not sure apart from cleaning data, what else we can do to avoid this error. Adding more information about the data, I have total 81 columns and around half a million rows. I dropped a row having all null values and not remaining data is null free. Now question is how to proceed with this error. Any suggestions?</p>
