Parameters

A parameter is a dynamic, user-controlled value that can feed into calculated fields, filters, or reference lines - letting viewers interact with a dashboard beyond simple filtering.

Creating a Parameter

Right-click in the Data pane -> Create Parameter...
Set data type, allowable values (list, range, or all), and a default value

Using a Parameter

A parameter by itself does nothing until it's referenced somewhere - typically inside a calculated field, a filter, or a reference line's value setting.

IF [Sales] > [Target Parameter] THEN "Above Target" ELSE "Below Target" END

Showing the Parameter Control

Right-click the parameter in the Data pane -> Show Parameter Control

This displays a slider, dropdown, or input box directly on the dashboard, letting viewers change the value themselves.

Common Use Cases

• Letting users switch the measure being displayed in a chart (e.g. Sales vs Profit).
• Building a "what-if" scenario, like adjusting a discount percentage.
• Setting a dynamic threshold for a reference line.
