You can create a pie chart in Excel and format it for a professional look. You can also rotate the chart slices for different perspectives.
To create an Excel chart, open a blank worksheet and enter the data, or open an existing worksheet that contains the data you want to plot.
Highlight cells containing the data. On the Insert tab, click on the inset pie chart icon and select a chart type from the drop-down list. The chart appears on the worksheet.
Edit the default chart settings by clicking on them. Right click on the pie chart and select Add Data Labels, and then Format Data Labels to change values of each section of the chart.
