Yeap, that's right. It helped, thank you very much.
So, for next generation, how to solve this problem in few steps:
1. Go to Qt Maintenance Tool (it is in the folder where Qt is install)
2. Run it
3. Choose Add components
4. Expand list for you version which you have installed. Charts are available from Qt 5.7 (correct me if I'm wrong)
5. Choose QtCharts (I also choosed Qt Data Visualisation)
6. Click next
7. Restart your Qt program
8. Click Build -> Run qmake
Now it should work![]()
