Excel's OFFSET function lets you create a reference that isquite literally offset from a starting point. It allows references to adjust dynamically to changes in your spreadsheet's data and structure.

However, if you add a series of data points to a spreadsheet, Excel doesn't know to include these on an existing chart. To include this data, you must manually add the series to the chart.

Pie charts work best when you're charting only one data series, when none of your data are negative, when your data features no zero values and when you have seven values or fewer.
