Section 6.1: Charts and Graphs
Graphs and Charts are very helpful for displaying information. To create a graph or chart,
Go to the Insert Tab.
Click Chart, then the type of chart you want to make.
Your chart will appear on your slide. To edit your chart, click on the chart and go to the top right corner. Click the 3 button icon next to Linked Chart and click Open Source. This will open a spreadsheet that allows you to change your data.
To change your data, click on your chart in Google Sheets and click the 3 button icon. Click Edit Chart. The Chart Editor will appear on the right side of the screen. There you can go to the Customize Section to add data and make changes to the pie slices.
The last step for making a chart accessible is by adding Data Labels. 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.
This table does not have any data labels on it. A person who is color blind may have trouble knowing the differences between the sections and categories.
This table has the data labels. Now a reader with low vision can still know what each category stands for without needing color.
After you have completed your chart or graph, be sure it has an alt text. You can make one by right clicking on the chart and clicking the Edit Alt Text button. In the alt text panel, explain your chart or graph in less than 150 characters. You can also include a link to a long description in addition to the alt text if 150 characters is not enough. 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.
