running statistics

[Bernd R.]

I have a series of values one at a time and would like to calculate
the average, SD and CV of these values. I use the "Statistics Express
VI", but I'm not able to configure it so that previous data is
included in the calculation and the calculation is updated after every
incoming data point. Actually it updates itself, but the calculations
are performed only with that one last value instead of including the
ones before.
Thanks
Bernd
