Connection between C++ and qml with parameters

[Mounika]

Hi all,
I am reading csv file and filling that data into list and map in the C++ class , i want to get to Qml for plotting data, how can it possible , please let me know.

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.

you need to declare and register both Class and Struct and convert QMap into a QVariantMap

To add to what @VRonin said, have a look at Data Type Conversion Between QML and C++.

Given your need, have you considered inserting the data in a model instead?
