Charts

Requirements

  • Color is not used as the only visual means of conveying information.  
  • Ensure all text and images of text has a contrast ratio of at least 4.5:1. 
  • Meaningful non-text context has at least 3:1 against adjacent colors. 
  • Design charts with color blindness in mind. 
  • Charts must have alt text. 

Important Info

  • Create charts using PPTs built-in chart tools.  
  • Avoid using images of charts whenever possible. 
  • Most charts will require short and long descriptions to fully explain the image. Please see Alternative Text/Long Descriptions for Complex Images for more information. 
  • Make sure chart labels have sufficient contrast. 
  • Red/green color blindness is the most common, so avoid green on red or red on green. 

Tips

  • Insert a chart using the ribbon: Insert > Illustrations > Chart. This will ensure screen readers announce the chart as a chart. 
  • Charts that contain color may need alternative visual designs such as different line styles, patterns, or symbols.
