Tables, Charts, and Graphs in Presentations
Use simple tables in the document. A simple table is a table with one column and row header. Complex tables are tables with irregular headers, merged cells, multi-level columns, or row headers, etc.
To add a table to your presentation:
- Go to Insert > Table. Click on the little arrow under Table to choose the size of the table.
- Insert the table with the desired number of columns or rows.
- To make the table accessible, it is essential to add the header rows. To add the header rows. Go to Table Tools > Design. Make sure to click on the Header row checkbox to let the screen reader know that the table contains the header row. If you have row headers, click on the First column checkbox.
Charts and Graphs
To create accessible charts and graphs, use the features available in PowerPoint. If you import the charts/graphs from Excel, they are inserted as an image. Follow the steps below to create a chart/graph:
- Go to Insert > Chart.
- Click on the Chart and choose the type of chart or graph you want to use.
- Once you click on the chart/graph, it will be inserted into the slide with an Excel pop-up of the data table.
- You can edit the data in the chart by editing the data table in Excel. You can also copy and paste the data from an Excel file into the data table.
- Use the Chart Tools on the top panel to edit the color scheme of the chart/graph. Make sure the contrast ratio is valid.
- To make this chart/graph accessible, it is essential that you add a data table. Go to Chart Tools > Design > Add Chart Element > Data Table. Click on With Legend Keys or Without Legend Keys.
- This will insert a data table below the chart/graph that the screen reader can navigate.
- You can close the Excel pop-up. If you need to change data, you can access it again by clicking Chart Tools > Design > Edit Data.
If it is not possible to add the data table, you can make the chart/graph accessible by adding an alternative text. This is covered in the alternative text section.
Please note that some charts, such as pie charts and scatter charts in PowerPoint, do not offer the option to display the data table. In that case, you can add a proper alternative text. You can also use the Chart Tools > Design > Add Chart Element > Data Labels > Data Callout option to make the chart readable by displaying the label along with the data.
