Is there any way to set the pyqtgraph ImageView X and Y range by code? By clicking right mouse button on ImageView in GUI program, there is an option to set the X and Y axis. However, in the Docs API Reference for ImageView there is no mention of how to set the X-Y range.

I think you're looking for setLimits() to constrain the view range. You can set the minimum/maximum range for the x and y axis using xMin, xMax, yMin, and yMax

plot_widget = pg.PlotWidget()
plot_widget.setLimits(xMin=1, xMax=5, yMin=0, yMax=100)

For instance with

plot_widget.setLimits(xMin=0, xMax=.5, yMin=0, yMax=400)

and with 

plot_widget.setLimits(xMin=.2, xMax=.3, yMin=0, yMax=125)

Thank you for advices. I found that ImageView doesn't have an option to set limits. To set limits for ImageView, it must be uses as PlotItem, example below

self.plot = pg.PlotItem()
imv = pg.ImageView(self.plot)

and now its possible to use setLimits, setXRange, setYRange or any other similar function to limit region.
