I am filling list with struct and map with key as int and value as list of class
ie.,
Qlist<Struct>
Qmap<int,Qlist<Class>>

i want to get that list and map in the qml to plot charts.

For the start read this and this

Especially this section will be of interest for you then.

Also if you want to access porperties in QML you should use types known to Qt's meta type system. Means registered QObjects with properties instead of your structs.

And btw: no need to post the same question on multiple forums.
