Embedding a graph into a GUI (Qtdesigner and Pyside)
I am new to stack overflow. This is my first post so please do correct me out if I am wrong. Will be precise and explain my issue.
I have a sensor which records, yaw and pitch and the recorded data has been processed and clipped according to the project requirements. I want to embed the graph which is being generated in the GUI. I am using Qt designer and Pyside to do this.
I did read up on pyqtgraph documentation and went through the examples,documentation and didn't get a good grasp of it.However I followed the steps,
"In Designer, create a QGraphicsView widget (“Graphics View” under the “Display Widgets” category). Right-click on the QGraphicsView and select “Promote To...”. Under “Promoted class name”, enter the class name you wish to use (“PlotWidget”, “GraphicsLayoutWidget”, etc). Under “Header file”, enter “pyqtgraph”. Click “Add”, then click “Promote”."
Now how to address the graphics view widget and pyqtgraph to plot a graph within the gui?
Here is my QtDsigner code:

# else:

Solution
You no longer have to create a PlotWidget object since graphicsView is, you just have to change:
pw = pg.PlotWidget()
self.graphicsView.pw.plot(pitch) #This is not working
to:
self.graphicsView.plot(pitch) #This is working
