For scroll bar to Barchart try like below
Chart Properties-> Presentation -> Select Enable X-Axis Scrollbar option
and for Pie chart
if you have many slices then it is different to plot the numbers, one option is to show numbers in Legend like
Chart Properties-> Presentation -> Select Show Legend & Show Numbers in Legend option
or try Pie Popout
Chart Properties-> Expression-> click on Expression and give 0.1 for Pie Popout.
Hope this helps you.
