PyQtGraph How to zoom in using a button

I'm using PyQTGraph along with PyQT5, and I've added a GraphicsLayoutWidget, with mouse events to add markers.



canvas_ruler = pg.GraphicsLayoutWidget()
formLayout.addWidget(self.canvas_ruler)
plot_ruler = canvas_ruler.addPlot(name="Ruler")

plot_ruler.hideAxis('left')

canvas_ruler.scene().sigMouseMoved.connect(self.mouseMoved)
canvas_ruler.scene().sigMouseClicked.connect(self.mouseClicked)
plot_ruler.setMouseEnabled(x=True, y=False)


What I would like to add, are 2 buttons, to zoom in and zoom out, currently the mouse wheel event, does zooming in/out. But I want to disable that and add 2 buttons for it. I probably should:



setMouseEnabled(x=False, y=False)


But I don't know how to trigger the zoom using code, I couldn't find it's APIs, like sigMouseMoved.connect.






python-3.x pyqtgraph

There's water in the way. – Roddy of the Frozen Peas Dec 12 '16 at 7:42 I presume the route is somehow Malaysia-East Timor-Darwin Australia and on. But even these fine fellas abikejourney.com have flown from Singapore to Australia. With the increasing difficulty in freighter tourism, this will be at least very challenging. – chx Dec 12 '16 at 10:01 add a comment  |  10 Is it possible to ride from Malaysia to Papua New Guinea by motorcycle.
