  4. Data labels are very important for accessibility purposes. You should always include a title, axis labels, data labels, and any other relevant labels that make the graph easy to understand. If data labels are not present, then readers will have fewer queues to help them read the information. Charts, tables, and graphs cannot be read by screen readers without their labels, so always add them. To add data labels, click on your chart, and click the Chart Elements Plus sign in the top right corner. Choose which data labels you want to use. Next, customize them so they are visible but does not distract from the chart itself.

When you are finished, check your chart to be sure that your font is accessible with a good size and contrast ratio to its background.
