Line Plot on a Waveform Graph with a Color Change Displaying a Crossed Threshold

This example copies data into two array. In one array all values above the threshold are set as "NaN" and in the other array all values below the threshold are set as "NaN." Both arrays are plotted on the same graph indicator and each array's properties, such as color, can be set independently, even though they appear to be the same line. This example is valid for both waveform graphs and waveform charts.

why not use auto-indexing
This example even gets better when auto indexing is used instead of connecting the number of elements to the N of the for loop and index from the shiftregister. If memory reuse is here more important (because it now has one memory copy less please state this in a discussion ! Every bit of an example should be used.

Works in Base Package
Contrary to the requirements listed above, this example works fine in the LabVIEW 7.1 Base Package. It doesn't need the Professional Development System.

Can we figure a way to do this in CVI?
This would be a neat feature to have in CVI. Can the NI Engineers come up with a parallel example?
