But what about if you want the chart title to change depending on what is selected? For example, you might be using slicers or filters to allow a user to choose which days of the week they want to see data for. In that situation you might want to add a title that shows which days of the week have actually been selected; this would be particularly important if the report uses filters, or if the report is going to be printed. Unfortunately the built in Title Text property can’t be used to display dynamic values but in this blog post I’ll show you how to solve this problem using DAX.
The solution isn’t trivial, but it is cool.
