Mashup - Set filter selection für Object

[schmidtj]

Hi,

i am building a mashup using the dev hub.
I need to put together different charts from different apps und i am getting the charts using getObject().

myApp.getObject('objKpi', 'cdYHGub', {noSelections: true, noInteraction: false});

However, i have a field which i need to filter differently per chart.
Usually i pass selections via the url in the iframe which displays my mashup.
This time though i need to have separate filters per chart.
I havent really found an option to do that. 

Example:
chart1 with filter sameField = X
chart2 with filter sameField = Y; 
chart3 with filter sameField = Z; 

Can somebody help me with that?
