Excel's default chart type is the column chart, although there are many other types from which to choose. A column chart might adequately display your data, but you should experiment with a variety of chart types to find the one that shows your data in the most effective way. A pie chart is an effective and easily understood chart type for comparing parts that make up a whole entity, such as departmental percentages of a company budget. You can call attention to individual pie slices that are particularly significant by moving them away from the other pieces, called exploding the pie. Change a Chart Type Quickly
