title: placing a Vector in a Scatterplot - Python
body: <p>I had used an optimization algorithm to do a binary classification. The algorithm had produced a hyperplane (vector or list) that separates the classes of a dataset into two. Now, I wish to include this hyperplane (vector) in the scatterplot of the dataset. I need a guide on this, please.</p>
  
  <p>Suppose the dataset is <code>X_test</code> with label as <code>y_test</code>. If the vector is say, <code>hyper = [a, b, c, d]</code></p>
  
  <p>I have my scatterplot as:</p>
  
  <pre><code>sns.set_style('white')
  sns.scatterplot(X_test[:,0],X_test[:,1],hue=y_test.reshape(-1));
  </code></pre>
  
  <p>I could actually use the above seaborn or matplotlib for the scatterplot. How can I accomplish this?</p>
