Tableau parameter

Описание: In Tableau, a parameter is a dynamic control that allows users to change a single value, such as a number, date, or string, in order to modify the behavior of a workbook or dashboard. Parameters are used to create interactive and flexible data visualizations and reports. Here are some key points about parameters in Tableau:

User Interaction: Parameters provide a way for users to interact with the data visualization by adjusting a parameter's value. For example, you can create a parameter that allows users to select a specific category, date range, or measure to display in a chart.

Dynamic Filtering: Parameters can be used to filter data in a visualization. By connecting a parameter to one or more data fields, you can dynamically filter the data based on the parameter's value. This enables users to explore data from different perspectives.

Calculations: Parameters can be used in calculated fields and formulas to perform various calculations or create conditional logic. This allows for more advanced data manipulation and custom calculations based on user input.

Dashboard Interactivity: Parameters are often used in Tableau dashboards to create interactive elements. For example, you can use a parameter to control the level of detail in a map or chart, switch between different views, or change the aggregation of data.

Customization: Parameters can be customized to provide a specific list of allowable values, control formatting, and allow for input through various UI elements like drop-down lists, sliders, or input boxes.

Actions: Parameters can trigger actions in Tableau, such as filtering other worksheets or dashboards when their values change. This creates a more connected and interactive experience for users.

Overall, parameters in Tableau are a powerful feature that enhances the interactivity and flexibility of your data visualizations, allowing users to explore and analyze data in a way that suits their needs.
