How can I hold on the maximum value of a signal?

[happy-student]

I measure for a certain time an analog signal, and after the measurement, I want to indicate the maximum value(amplitude) of the whole measurement.
MinMax.vi or Max&min(at Comparison) indicate only the immediate maximum value, but not the maximum value of the whole measurement.
Thanks for help!

On the Array palette, look at Array Max & Min.

If you're taking repeated measurements in a loop, use a shift register. Look at the Calculate Max.vi example that ships with LabView. To find the examples, from any LabView window, goto Help >> Find Examples >> Search, then enter SHIFT REGISTERS in the box labeled Type a keyword to find:
