Interesting!
The first thing that comes to mind is to use two separate viewboxes, like:
import pyqtgraph as pg
pg.mkQApp()
w = pg.GraphicsLayoutWidget()
w.show()
v1 = w.addPlot()
v2 = w.addPlot()
v2.hideAxis('left')
v2.setYLink(v1)
offset = 450
def updateRange():
xrange1 = v1.vb.viewRange()[0]
xscale = (xrange1[1] - xrange1[0]) / v1.vb.rect().width()
xrange2 = xscale * v2.vb.rect().width()
v2.setXRange(offset, offset+xrange2, padding=0)
v1.sigXRangeChanged.connect(updateRange)
d = pg.np.random.normal(size=600)
d[100:500] = 0
v1.plot(d)
v2.plot(d)
v1.setXRange(0, 200)
It would take a bit more work to make that look like a seamless plot,
though.
