The Bubble Chart View displays a set of bubbles plotted according to two variables, one on the horizontal and the other on the vertical axis of the chart. In addition, the size of the bubble can be set to a variable in your data, and a playback control at the bottom of the screen will play chronologically through a series of Date values.
In the "Views" tab of your Visualization, click the Bubble Chart thumbnail to configure a Bubble 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 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:
- X-Axis: This menu determines the Field to use to map data along the X-Axis in the bubble . This option accepts Number Fields only, and for the best results the data should be continuous.
- Y-Axis: This menu determines the Field to use to map data along the Y-Axis in the bubble . This option accepts Number Fields only, and for the best results the data should be continuous.
- Bubble Size: This menu determines the Field to use to determine the size of each bubble in the bubble . This option accepts Number Fields only.
- Chart By: This menu determines the Field to use as the title for each bubble in the bubble .
- Group By: This menu determines the Field to use for the playback control. This option accepts Date Fields only.
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.
