You can add a chart to your presentation to display complex information, such as statistical information and data analysis. Pie charts are used to represent different sections of a whole data set. When using a pie chart in a slide show, you can animate each section of the pie to appear individually. This allows you to speak about each category separately as it appears, placing emphasis on each category of the pie rather than the entire chart.
Click the slide you want to contain the chart. Select "Chart" on the "Insert" tab in the "Illustrations" group.
Choose a style of pie chart from the "Insert Chart" screen. There are six styles of pie charts available to choose. These are "Pie," "Pie in 3-D," "Pie of Pie," "Exploded Pie," "Exploded Pie in 3-D" and "Bar of Pie."
Replace the sample data in the Excel worksheet that appears. Click the "Sales" cell, B1, of the sample data and enter a new "Column" heading to change the label of the chart. Replace "1st Qrt," "2nd Qrt," "3rd Qrt" and "4th Qrt" in cells A2 through A5. Replace the sample data with your data.
Click "File" and then "Close," or click the "Close" button in the upper-right corner on the Excel spreadsheet to close the data. The PowerPoint chart automatically updates based on the data entered.
Select an animation from the "More" menu on the "Animation" tab in the "Animation" group.
Click "Animation Pane" on the "Animation" tab in the "Advanced Animation" group.
Select "Effect Options" from the drop-down arrow next to the animation in the "Animation" pane.
Click the "Chart Animation" tab in the "Effect" screen and choose "By Category" in the "Group By" field.
You can enter more category labels and data in the Excel spreadsheet. Just make sure to click on the lower-left corner of the blue outline and drag to encompass all of your data. This sets the data range.
