How to show limit-violation in Graph?

[OnlyOne]

Hello,
i have a oszi-measuremt which is displayed in a graph, then i created to extra waveforms for upper- and lower limit which are shown in the same graph.
I attached an example where all 3 traces are shown but the mesaurement (yellow) is NOT between upper and lower limit.
What i want to do is to change the color at the points where the measurement-trace is not between the limit-lines. Currently measuremnet is always yellow.
Is there an easy solution for this in LV 8.5?
Thanks

I would use Limit Testing.vi to solve this task :
Functions palette >> Waveform >> Analog Waveform >> Waveform Measurements >> Waveform Monitoring

A few examples ship with LabVIEW :
LV menu >> Help >> Find Examples... >> display the Search tab and make a search for Limit

Hi JB,
thanks for your answer.
There are a ot of goof examples and "Frequency Analysis of an Filter Design" looks extactly like what i need.
But i cant find out how to connect the examples to my measurements.
I tried to connect my traces into the example but i cant get it run.
Can you help me how to use the NI-example with my example-data?
Thx for the help

Here's a modification of your VI to use the limit functions.
