NON-TEXT-CONTENT-13: Ensure that charts and graphs do not rely on a single sensory characteristic.
How to test
- Identify instances of charts or graphs and confirm that each area of the graph or chart has more than one way to differentiate their information (e.g. combinations of color, pattern, or text).
- Where the graph or chart is purely decorative.
How to fix
Use more than one sensory characteristic to differentiate different areas of graphs and charts. For example, use both color and and patterns/texture (hash, lines, crosses, dots, etc).
