How to Show Multiple Groups in Combo Charts

[#1]

Dear All,

I have build a Combo Chart with 8 Expression in Which 4 are Grouped together and Represented as Bar and other 4 are not grouped and they are Line.

Now when i Select a expression from group i should only see relavent Expression from the Individual Expression.

Example :

My expression in Group are : FT, CBM, MT, TEU

and Individual Expression as : FT / Voy, CBM / Voy, MT / Voy, TEU / Voy

Now when i will select FT from Group it should also show me only FT / Voy .

Regards,

Pranav
