Chart with more selections month

[danosoft]

Hi i add the example to work in attachment, the problem is that:

Like you see i have 2 charts and 2 list boxes selections (ANNOTEMPO,MESETEMPO)

if i choose one single month, all is ok, the problem become when i choose more months.

For example i choose annotempo = 2018  and mesetempo = 3 and 9

- in my "Chart - last month" i want to see the value of my MAX month i selected (so in this example i want to see only value of my month 9)

- in my "Chart - first month" i want to see the value of my MIN month i selected (so in this example i want to see only value of my month 3)

how can i do that?

Thanks
