Creating an accessible pie chart video overview
This video will provide a detailed walkthrough of how to make an accessible Pie Chart in PowerPoint.
An accessible pie chart includes the following elements:
- Do not rely on color alone
- Alternate text
- Data table is available
Example of accessible pie chart (image)
This image represents an accessible pie chart that includes labels and patterns.
Add labels to a pie chart
There is no reason to hide or confuse data in a pie chart. Be specific and direct and add data labels to all data points in any chart!
- Right-click the pie chart
- Select Format Data levels
- Select the best options for the data labels
Add patterns to a pie chart
Patterns are more accessible to a wider array of people with disabilities. Instead of relying on color alone (which is an accessibility failure) – use a pattern and a color.
- Right-click the Pie Chart
- Select Format Data Series
- Choose the appropriate pattern and color
Add alternate text
- Right-click the entire chart object
- Select alternate text
- Enter a detailed alternate text
Do you plan on converting the PowerPoint to another file type like PDF?
You might consider inserting the Pie Chart as a flattened image and providing alternate text instead. Screen readers can have difficulty reading the contents of a pie chart within the PPT itself.
