title: Excel Graph with custom standard deviation
body: <p>I have 2 columns, one with my data points, other with the standard deviation for each data point. How do I make a line plot on excel with error bars equal to each point's perspective standard deviation?</p>
  
  <p>e.g.</p>
  
  <pre><code>Col-1  Col-2
  1      0.1
  2      0.2
  3      0.1
  </code></pre>
