Look at the screenshot http://postimg.org/image/pc6pu0dlj/
My question is simple, but I can't do this, the way I want. How and what should I do, to make the gaps in the chart? At the screenshot above I insert value -200 for these three signals, but there is - as you see - a line connecting the visible value to the not visible. I want to get something similar to this http://postimg.org/image/inknhw54j/ Is there any possibility to do this?
Because these data come from Network, and if datagram will not income, I want to leave empty graph, but with the previous drawn signal, and if data income again, the rest of the signal should be drawn, so this can be consider as discontinuous signal.
Thanks in advance,
