How to use filter for a graph through expression?

[Venkatsj]

Region	Document no	Days
Germany	1	1
Germany	23	2
India	25	3
Australia	35	2
US	456	3
Netherlands	3	45
US	2	21
India	4	52

For the above mentioned table i want to have a line chart as "days" as measure and " Document Name" as dimension. But need this graph only for particular region for e.g. India without using filter pane. Is there a expression I can use ? Kindly help, Thank you

Please use 'Set Analysis' in your expression.

e.g. Sum({<Region={'India'}>}Days)
