Strech image to window size in pyqtgraph

[rob.l...@gmail.com]

I'm currently trying to create a PyQtGraph gui to plot an image repeatedly as new data comes in using code similar to this:

self.app = QtGui.QApplication([]) 
self.win = QtGui.QMainWindow() 
self.win.resize(800, 600) 
self.imv = pg.ImageView() 
self.win.setCentralWidget(self.imv) 
self.win.setWindowTitle('My Title') 
self.timer = QtCore.QTimer() 
self.timer.timeout.connect(self.check_for_new_data_and_replot) 
self.timer.start(100) self.win.show()

then each time I get new data I draw the image:

self.imv.setImage(self.data_array)

One problem I'm running into is that my data array usually has a skewed aspect ratio, i.e. it is usually really "tall and skinny" or "short and fat", and the image that is plotted has the same proportions.

Is there a way to stretch the image to fit the window? I've looked through the documentation for ImageView and ImageItem, but can't find what I need. (Perhaps it is there, but I am having trouble identifying it.)
