You can use charts to summarize large sets of data in an easy-to-follow visual format.
You're not stuck with the chart you create; if you want to change it, you can.
If you format a lot of your charts the same way, creating a chart template can save you a lot of work in the future.
Adding chart labels and a legend makes your chart much easier to follow.
If your chart data represents a series of events over time (such as monthly or yearly sales), you can use trend line analysis to extrapolate future events based on the past data.
A PivotChart enables you to rearrange your chart on the fly, emphasizing different aspects of the same data without having to create a new chart for each view.
Excel 2007 enables you to quickly create and modify common business and organizational diagrams, such as organization charts and process diagrams.
