Parameters
Parameters are like variables/placeholders in Tableau, which give the end user the ability to control the view or data that is shown as part of the report. They allow you to customize your view, adding interactivity as well as flexibility to the workbook. Parameters are used to replacing a constant value from the view with more variable/dynamic values, which are controlled by the end user. They can take any data type: strings, integers, floats, dates, or any varchars. They can easily be confused with filters but the major difference between parameters and filters is that, with filters, the data gets filtered from the view so that it only shows for the filtered values, whereas with parameters, the variables only act as a reference. Parameters control the value of the variable created instead of filtering on the data.
To use parameters in the view, there are four steps that you need to perform:
- Create the parameters based on the requirements.
- Show the parameter...
