How to get interactive update (live-plot) for pyqtgraph in jupyter?

[Eugene E.]

Hi all!

I have the data stream I would like to plot immediately in pyqtgraph, here is an MWE:

%gui qt

import numpy as np
import pyqtgraph as pg
from time import sleep

win = pg.GraphicsWindow()
qplt = win.addPlot()
curve = qplt.plot()


for i in range(8):
    sleep(.5)
    curve.setData(np.random.random(size=16))

but it only updates the plot window once the cell calculation is complete. How to force an update and a redraw?
