Top K (range) in chart with a slider and two variables

[#1]

Hi all,

can I view in a bar chart only K elements with a slider and two variables:
vMinRange = X

vMaxRange = Y

where K= Y-X

but only K elements from Yth to Xth.

Example:

Expression= sum(Sales)

Dimension= Department

X=3

Y=9

K=6

in the chart i want view only 6 bar, from 3th to 9th ranking by sum(Sales) descendent.

Thank you all.
