We will cover tables first, but you can scroll down for info on charts.
Tables can be great ways to organize information so it is clearer and more easily digestible. The reader's eyes can scan across and down rows and columns quickly, instead of reading a paragraph. Simple tables (tables with one row of headings or one column of headings or both) are usually the easiest for screen reading software (like JAWS) to decipher.
Assistive technology, such as screen readers (JAWS), read tables in a linear form. For example, the screen reader begins reading from the first row of the table and then progresses left to right across the columns. When the row ends, it continues to the start of the second row, and so forth.
Also, screen readers always assume that the first row and column of a table contain heading information. Use Styles to designate which row(s) and column(s) are your headers. For help with using Styles, visit Module 2, Lesson 2: Styles.
If the table continues on to another page, make sure to turn on the "Repeat Header Rows" function. See below for instructions on how to do this.
Just like with images, if your presentation includes charts or graphs you must add alternate text (alt text) to explain their meaning, or provide a link to a longer description. For more information on what alt text is, see Module 3 - PC Lesson 4 - Images.
To add alt text to your chart or graph:
