splitting pivot chart

Hi nastslay,
Welcome to the forum.
If all the info is still in the same pivot table, you just create several copies of that pivot table and adjust each one according to the desired results. Then create the pivot chart for each pivot table and you can collect all of them in something like a dashboard. Or even add a slicer and make sure that it is connected to all your pivots and this way you can create many tiny charts as much as you want.
If it is still not clear, just upload a sample file to show you an example.
