You can do it in both - Chart expression and script expression.

Hi Baarathi V,

It is ideal to have it in the script if you are particular with performance.

Its also possible to do in the listbox object, however if you have millions of rows and will use that calculated listbox as filter to all sheets you have, you have a potential performance issue
