Can I display only negative values in an X-Y graph

[kingsballer12]

I have my graph set up to run reading two arrays. It is a sine on sine wave and I only want to display the negative results. Is there a way to do this? Is it possible with something like a scan from function? In the end I will be linking this up to an absolute value and having only the negatives be positive, but getting the graph to display only the negative values is the first step.

You can use the Threshhold 1D Array to filter out all values greater than 0.

And/or replace the positive values with NaN (not a number). NaN doesn't get plotted on the graph.
