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.
