Suzane is using the express VIs she does not see what you are
suggesting. The express does the point by point analysis. I
had tried that but got the same flakey looking results. I just
took the chart history and ran a mean on it. I may have wired it
up wrong, cause I was suprised the mean was so rocky if the mean pt by
pt was working properly. Anyways, this should accomplish the job.
