I would like to add this as a comment to the accepted post:

If you are using python to build your project and process the .ui files with pyuic5 it might be the case that pyuic5 leaves you with an error message stating that QtChart.QChartview could not be found. This is the workaround:

Go to the site-packages/PyQt5/uic/widget-plugins directory, it should look something like this:

/widget-plugins/
  __pycache__/
  qaxcontainer.py
  qscintilla.py
  qtcharts.py  <- create this file by copying qtquickwidgets.py and renaming
  qtprintsupport.py
  qtquickwidgets.py
  qtwebkit.py

qtcharts.py looks like this (you have to edit the file):

# copyright information

pluginType = MODULE

def moduleInformation():
    return "PyQt5.QtChart", ("QChartView", )
