title: How do I create an Excel chart that pulls data from multiple sheets?
body: <p>I have monthly sales figures stored in separate sheets.  I would like to create a plot of sales for multiple products per month.  Each product would be represented in a different colored line on the same chart with each month running along the x axis.</p>
  
  <p>What is the best way to create a single line chart that pulls from the same relative cells on multiple sheets?</p>
