Accessibility Features in SAS/GRAPH

SAS/GRAPH includes accessibility and compatibility features that improve the usability of the product for users with disabilities, with exceptions noted below. These features are related to accessibility standards for electronic information technology that were adopted by the U.S. Government under Section 508 of the U.S. Rehabilitation Act of 1973, as amended, and recommended by the Worldwide Web Consortium (W3C) Web Accessibility Initiative (WAI).
When you are sending output to the HTML destination, and you are using the JAVA or ACTIVEX device, you can specify the ACCESSIBLE graphics option to generate descriptive text and tables of summary statistics for graphics output. SAS/GRAPH writes the text and table to the HTML file and creates a footnote to the bottom left of the graph that provides a link to the information. Neither the footnote nor the text and table are visible on the HTML page; however, both are detected by accessibility aids such as screen readers. You can display the text and table by positioning the cursor over the graph, and then pressing the tab key followed by the enter key. The text and table are also displayed if you move your mouse pointer over the footnote, and when the mouse pointer changes shape, click on the footnote. For more information, see ACCESSIBLE.
The data in the summary statistics table might not be ordered in the same way as bars or midpoints shown in the graph, or the midpoint labels in the graph might not exactly match the values listed in the table. If an exact match is preferred, the programmer can sort the data or apply a format to graph values before generating the graph.
All known exceptions to accessibility standards for the ActiveX control are as follows:
  • The software output does not disrupt or disable activated accessibility features of other programs or the operating system, except that it does not inherit user settings for color and contrast, such as a high contrast operating system theme.
  • Most interface elements, including menu bar options and short-cut keys, are read by a screen reader. However, not all elements are read. Some exceptions include:
    • Labels associated with the buttons
    • Column headings in the list view in the Edit Data dialog box
  • When the software output is displayed on a system where a user has modified the system color and contrast setting, those custom selections are not inherited. However, the programmer who produces the graph can provide style options to accommodate accessibility needs.
    When high contrast mode is invoked with a black background, some icons may not be displayed crisply.
All known exceptions to accessibility standards for the MetaView applet are as follows:
  • The Metaview applet does not honor the high contrast black color scheme.
