Providing Text Equivalents for Charts and Graphs
Charts and graphs present data as images or client-side image maps with links to navigate to details about the data. Because charts and graphs typically display significant amounts of data, providing alternate text labels for the chart or graph images is usually not enough to make the data accessible to people using screen readers. To make charts and graphs more accessible:
-
Do not use ASCII images to display charts and graphics; use the objects that are provided in PeopleTools.
-
Do not use color alone to convey information in charts and graphs.
See Providing Alternatives to Color Coding to Convey Meaning.
-
Provide textual information to describe the content of charts and graphs.
You can insert a static text field to describe the charts and graphs, but also consider displaying the underlying table information of the chart or graph in a grid format when the Accessibility Layout option is set to Screen Reader On. This method ensures that users in Screen Reader On mode get the same information that the chart or graphic image conveys.
Note:
The label that you specify on the Label tab of the Chart Properties dialog box is for information-only and does not appear at runtime. This label appears on the control order list on the Order tab of the page definition and any page definition report that you print.
