Thanks for the fast reply! I tried to add that line but didn't work. I then tried to apply it to the plot item and to the view box, but on both I get the error:
plotWidget.getViewBox().setBackgroundBrush(QtGui.QBrush(QtCore.Qt.transparent, QtCore.Qt.NoBrush)) AttributeError: 'ViewBox' object has no attribute 'setBackgroundBrush' Maybe I misunderstood what you meant by doing the same for the ViewBox? Thanks again!
