  <p>I want to draw barplot using seaborn catplot and want to display the regional data in 4 x 4 matrix. Following is my code:</p>
  <pre><code>import seaborn as sns
  sns.catplot(data=df,kind='bar',y='OBJECTID',x='crashYear',col_wrap=4)
  </code></pre>
  <p>When I ran the above code, it thows me following error:</p>
  <pre><code>ValueError: Number of rows must be a positive integer, not 0
  </code></pre>
  <p>I am not sure where I made the mistake. Could anyone help me in fixing the issue?</p>
