Hello, so I first create a qwidget which I promote to HistogramLUTWidget, right? In the dialog window I choose the base class name as "QWidget" the Promoted class name to "HistogramLUTWidget" Do I use the pyqtgraph.h as Header File or I have to use another one? I attached a snapshot of qt designer. The qwidget is called wu.
[image: Screenshot from 2020-07-23 21-29-31.png] Finally I have to insert the widget into my code: uic.loadUi(‘CEtb26.ui’, self) self.wu = self.findChild(HistogramLUTWidget, 'wu') self.wu = pg.HistogramLUTWidget(fillHistogram=False) Is it correct?
