Understanding Parameters in Tableau

A parameter in Tableau is a dynamic input that allows you to replace a constant value in calculations, filters, and reference lines with a value chosen by the user. Parameters offer interactivity and flexibility to your Tableau visualizations by enabling users to control certain aspects of the data.

How to Use Parameters in Tableau

Here's a step-by-step guide on how to use parameters in Tableau:

1. Open Tableau and Connect to Data:

• Launch Tableau: Start by opening Tableau on your computer. Create a new workbook or open an existing one.

• Connect to Data: In Tableau, connect to your data source, which contains the dataset you want to work with.

2. Create a Worksheet:

• Worksheets: After connecting to your data source, create a new worksheet by clicking on the "Worksheet" tab.

3. Create a Parameter:

• Parameter Option: In the worksheet, right-click on an empty space in the "Data" pane, and select "Create Parameter."

4. Configure the Parameter:

• Name and Data Type: Give your parameter a descriptive name and choose its data type. Common data types for parameters include Integer, Float, String, or Date.

• Current Value: Set the current value or initial value for the parameter.

• List of Values: Define a list of allowable values for the parameter. These values can come from a field in your dataset or be manually entered.

• Display Control: Choose the display control type, such as a drop-down list, slider, or type-in box, to allow users to interact with the parameter.

5. Use the Parameter in Calculations:

• In Calculations: You can use parameters in calculations by referencing the parameter name. For example, you can create a calculated field that multiplies a measure by the parameter value.

6. Create Parameter Actions:

• Parameter Actions: You can use parameter actions to link a parameter to a worksheet or dashboard action. This allows users to change the parameter value by interacting with a visualization, driving dynamic changes in the workbook.

7. Customize Parameter Interactivity:

• Parameter Interactivity: Customize how users interact with the parameter by setting up actions and filters that respond to parameter changes.

8. Save and Share:

• Save Workbook: Once you've set up parameters and integrated them into your worksheet or dashboard, save your Tableau workbook.

• Share: You can share your workbook or export worksheets as images or PDFs for use in your AP coursework.
