Chart on select data

[ts3st1000]

Hi, I am trying to plot a chart on a limited data. Here is an example. in the database, i have a table that looks like:

country	product	sales
Japan	type1	10
China	type2	11
Malaysia	type3	12
Vietnam	type4	13
Indonesia	type1	14
Thailand	type2	15

I would like to plot Sales by country where product is different from type 2 and type 3, meaning i would like to limit the chart to this table

country	product	sales
Japan	type1	10
Vietnam	type4	13
Indonesia	type1	14
Thailand	type2	15

Could you please suggest an expression to do this. thanks very much.

Set Analysis Expression -

=Sum({$<[Product]-={'type2','type3'}>} Sales)

Normal Expression

=If(Not wildmatch(Product ,'type2','type3'), Sum(Sales))
