Charts are not accessible in this release.
Because the MSAA role ROLE_SYSTEM_CHART is not supported by Flash Player at this time, charts cannot declare themselves as such.
Sample Accessible Application
Below is an embedded application built to showcase accessibility. To experience this application properly, you must have a screen reader installed and be familiar with how to use it. Accessibility was developed with JAWS for Windows as the primary screen reader. Installing the JAWS Flex Scripts is highly recommended to obtain the most reliable results.
