Highlighting the Max and Min Values in Tableau

You might have seen charts like this...

Whereby, we have three lines charts. One showing the average performance, and the rest showing the maximum and minimum values recorded for a specific timeline - could be month, month-year, year etc.

Watch the video for details.
