Adding Tableau Parameters to a Custom View
Tableau parameters are one-way bindings that bind from a VDL view to the tableau workbook. You must define parameters in the Tableau workbook and in the view .vdl
file. You can use <vdl-tableau-parameter>
components within <vdl-tableau>
to set parameters per visualization. The value can be an expression, which will update the visualization each time it changes.
- Float
- Integer
- String
- Boolean
- Date

Adding a Tableau parameter
- In a Tableau workbook, create a new parameter from the drop-down arrow on the Data pane.
- Specify the data type, current value (this will be ignored when viewing the visualization in Xpress Insight), and value when the workbook opens.
- Define the display format to use in the parameter control.
- Define how the parameter will accept values, All is a simple text field, List will provide a list of possible values to select from, and Range allows you to select values within a specified range.
- Click OK. The new parameter will be shown in the list of filters for your workbook.
- Save the workbook and close Tableau.
- Open the custom view containing a Tableau visualization in Xpress Workbench. Drag a Tableau Parameter component from the palette into a Tableau component in your view.
