Regarding QtCustomPlot for plotting the data in real-time

[user_edu]

I'm making certain changes to the existing code on BLE heart listener application. I am interested in plotting the values of the heart rate measurement characteristic in real-time. I followed the basic tutorial on QCustomPlot for real-time plotting of the data, however, I am not sure about how can I use it with QtQuick. I mean in the main.cpp, already a view will be handled which allows user to select the relevant device from the list of available BLE devices. So should I create another .cpp file for plotting purpose and create the object of that class in the class which is getting the heart rate measurement characteristic value. I am very confused about how can this be achieved. Any kind of guidance or pseudo code will help. Thank you.

You will not be able to use the QCustomPlot widget inside the QML Window.

So can I create another .cpp in the same project for the window. Or any other suggestion that can be considered to implement the plotting functionality, can I use QWT?
