differnt colur on line in graph during signal lost

[NearSpace]

I have try to create graph and plots in a way like this : if I have signal in the line is green if I lost signal the line have to change to red and the continue to plott the last value in time and when the signal is back i goes back to green and continue to plote the new values, and what I will se is the signal gap in red in the green plotted line and there for if I plot over 24 hours I can see the red aeras in the green plotted line when there have been signal lost.

Have any one donne this or it is some function in Labview I have found yet ?

Lars,

Use two plots on one graph.  One red and one green.  On the green plot make all the points where the signal is lost have the value NaN (= Not a Number).  Similarly on the red plot make all the points where the signal is PRESENT have the value NaN.  The NaN values do not appear on the graph so it will make the two plots look like one with two colors.
