How to Create a Pie Chart

  • Start with what you want to illustrate. The main topic will be the title of your chart.
  • Gather the data. Pie charts depict percentages. Make sure your percentages add up to 100% and get rid of any rounding issues that would make the total something other than 100%. SmartDraw allows you to write the percentage directly into a pie chart template or you can drag the edge of a wedge to make it bigger or smaller.
  • Consider creating a legend. If a wedge is too small to hold text, you can create a label and draw a line identifying the appropriate slice. Alternatively, you can create a key that shows what each color represents.
