Interactive Dashboards with Parameters

In order to create interactive dashboard, it is essential to understand what parameters in Tableau are.

Key Features of Parameters

• Interactivity: users can adjust visualizations or queries dynamically, enhancing the flexibility of analysis;
• Data manipulation: parameters allow you to modify values used in calculations, filters, or reports in real time;
• Integration with calculations: they can be incorporated into Calculated Fields for dynamic and responsive formulas;
• Support for various types: Tableau parameters can handle numeric values, strings, dates, or Boolean variables, depending on the requirements of your analysis.

Additional Notes

While parameters themselves do not affect data directly, they become powerful when combined with calculated fields or used as dynamic filters. For instance, you can create a parameter to adjust a percentage value dynamically or switch between different categories for comparison.

You can experiment with parameters in your dashboards to enable "what-if" analysis and provide interactive, user-driven insights.
