title: Add totals line to pivot chart in Excel 2010
body: <p>I have a very simple pivot table that basically sums the hours of all the data records and pivots them with month as a row label and billable/non-billable as a column label.  The pivot table actually shows a totals column which is the sum of billable hours and non-billable hours by month.</p>
  
  <p>I created a pivot chart to represent the data, and it includes lines for billable hours and non-billable hours, but for some reason I can't get a third line to show the total hours.  The numbers exist in my pivot table, but I'm just not sure how to get those data points to graph on the chart.  Based on my research, it seems like a calculated field might do the trick, but that's frustrating--I hate to add a calculated field to calculate a value that's already displayed in the pivot table (though I'd do that if I had to--just couldn't get that to work either).  Any suggestions?</p>
