The sankey diagram is a flow diagram, in which the width of the arrows is proportional to the flow rate.
The following is a list of the fields in the View Properties box in the dashboard designer for sankey diagram. There are some required fields to be set for each created view.

Example: Using Controlled By Field
The sankey diagram allows you to view the flow rates between fields. If there are too many flow rates, it can be confusing and hard to see the flows clearly. You can use the “Controlled By” field is to select to un-select some fields temporarily to gain better view of the flow.
Assuming the controls has been created. In the “Controlled By” property, click on the “+” icon below it and select the appropriate controls from the drop-down list.
In the dashboard, click on the “>” icon on the upper left of the dashboard to show the list of controls selected in the “Controlled By” property. Click on the icon next to the control to display the list of fields. Select the appropriate checkboxes in the controls.
You can invert the selection by clicking on the icon in the control. To remove all selected fields, click on the icon.
Click on the icon next to the control to hide the selection. This will cause the control to revert back to the original view. To hide the controls but leaving the selection intact, click on the “<” icon on the upper left of the dashboard.
