Grouping the dimension based on other dimension in bar chart

[#1]

Hi All,

I have a scenario where i want to group the values of site based on the country in which the site present.

When i m selecting a country. It is showing proper results.

If we say the example of Country China, it is having sites like 157,161,170,190,193.

But if i dont select any country is it not showing  proper result in bar chart.

Basically i m trying to goup the site based on country. It is not showing proper result?

Anybody knows wht will be the problem?

Attached is the sample qvw file.
