Скачать или смотреть How to Build Dynamic Parameters in Tableau

Parameters in Tableau are powerful inputs which allow the user to customize visuals in a number of ways. They can change variables in a calculation, modify a filter or even move a reference line!

For some parameters (like dates), it makes sense to have the value update whenever the workbook is opened. For example, you might want the parameter to default to 'This Year', 'Today' or 'Last Week'.

If you have a scenario where it would be handy to have the default parameter selection update automatically, check out this video to learn how you can create dynamic parameters!
