import time
qapp = pg.mkQApp()
proc = mp.QtProcess()
rpg = proc._import('pyqtgraph')
win = rpg.GraphicsWindow()
plot1 = win.addPlot()
curve = plot1.plot()
curve.setPen('r')
win.show()
x = np.linspace(0, 10, 10)
y = np.linspace(-5, 5, 10)
curve.setData(x,y)
# you need to process and set data and call processEvents() in the loop
while win.isVisible():
y = y + np.random.random(10) # comment out this row not to update with
different value
curve.setData(x,y) # comment out this row not to update with different
value
qapp.processEvents()
