Defining variable to be used in few places

Question

Is there functionality in Tableau to create a variable that can be used in a few places by referring to its name? I'm asking because I need to prepare a dashboard and the data loaded and displayed on the dashboard can contain two different variables in a column called value. So I would need to define such a 'variable' that would be filled with the type of value column (ex. type 1 or type 2) and use it as an axis name, in a tooltip, etc. Of course, I'm trying to avoid a necessity to change all the axis names and tooltips manually.

In Tableau, they are called parameters. Please refer to the following articles to learn more about this. Refer to the second link for your query
