The Pie Set View is a collection of pie charts, each of which divides a circle into segments with the length of each segment representing a proportion of each category to the total sum of all data.
In the "Views" tab of your Visualization, click the Pie Set thumbnail to configure a Pie Set 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 two tabs in the settings on the left: "Controls" and "Descriptions".
The "Controls" tab lets you configure how your data will appear in your Visualization.
"Configure Menus" is where you can edit the Fields users will have access to in your View. For each option selected in the drop-down menu you will find a list of Fields. Select the checkboxes to show or hide Fields in the corresponding menu of your View, and click the home icon to determine the initial setting for your View. (To edit the Field name, return to the Fields tab in the main menu of your Visualization.)
In the drop-down menu you can select these options:
- Group By: This menu determines the Field to use for the wedges in the pie charts. The Fields you turn on for this setting should be a category Fields.
- Chart By: This menu determines the Field to use for determining the individual pie charts. For example, if this Field is "Name", then there will be as many pie charts as there are names in your Dataset. The Fields you turn on for this setting should generally be nominal ("Text") Fields.
- Aggregate By: Determines what to base the size of the wedges on. This is normally set to "Number of Items" by default, in which case Gist will sum the number of times a particular match occurs. If you have a Number Field that you would prefer to aggregate by (for example population), set the default to that Field.
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.
