Thanks to everyone for their help!

Looks like I'll be using the Build arb waveform Detlef suggested...

Thanks to all.

Alex.

Hi Alex
I have done such things in the past by transforming the 12 points 1201 points.
Not knowing the shape of your mask makes it difficult to advise on how to generate the mask.
But in essence each point is expanded to 100 points so that you can use the comparator object to check for fails And the xy chart to view the data with the mask overlay. But as long as the sum of the mask shape points equals the data length then its game on!

Good Luck Mike

Hi all,

Struggling a bit here, I hope someone can help....

I'm using a Waveform (Time) display object. Into this, I put my limit lines
(12 co-ord points, connected), and 1201 co-ord points of instrument data.

Now i'm used to using XY charts, so each array on the input has the same number of elements, so all I've got to do is run a 'for each' on each pair of elements and check the data's not higher than the limit line for each respective point - easy.

but problem with this is I have an unmatched number of co-ords (limit lines have 12 co-ords, and data has 1201) - so how can I check if my data is below the limits?

Any ideas anyone??

Many thanks in advance for help.
