But where to set the expression

use in Layout of a chart

and you can also display some message after more than 3 selections

You can do two things

1) you can hide chart on more than 3 selections ( chart1 in attached file)

2) you can display some message on more than three selection ( chart2 in attached file)

hope this helps
