The Area Chart View is similar to the Line Graph, with the exception that the area below each line is filled with a color.
Note that this View currently only works with aggregate data. Aggregate data is data that includes only Number fields, or a single Text field in addition to other fields (Date, Number, Percent). (For more information on individual and aggregate data refer to Preparing your data for Gist.)
In the "Views" tab of your Visualization, click the Area Chart thumbnail to configure a Area Chart View for your Visualization.
The configuration window will appear with the settings on the left and a preview on the right. The preview will automatically update as you make edits.
There are three tabs in the settings on the left: "Controls", "Annotations" and "Descriptions".
The "Controls" tab lets you configure how your data will appear in your Visualization. This tab includes the following options:
- Display Units
- Configure Menus
Selecting the “Areas” drop-down will list the Fields that can be selected to be plotted as areas on the chart.
If applicable, the “Display Units” control allows you to add a percent symbol ("%") to your Y-Axis labels.
In "Configure Menus" you can control how your data will be shown on the X-Axis via the "Chart By" menu.
The "Annotations" tab lets you add annotations to your View. You can add overlay text which appears at the top left of the chart. You can also add benchmarks that overlay a dashed line and label over your chart at the Y-Axis level that you specify.
The "Descriptions" tab finally lets you add a description and meta-description to your View. The description will appear at the top of the View and is a good way of orienting users to what they can hope to take away from the View. The meta-description lets you add a write-up of the key takeaways from your chart for screen readers.
