Display only max value in numeric indicator

I am working on a setup that reads in the RMS and Peak to Peak for a sign wave from a transducer.  The problem is that there are lots of minor fluctuations in the values displayed in the attached numeric indicators.  I am searching for a way to have a numeric indicator that displays on thy the highed value, and another that displays the lowest value collected during the run (so if the numbers range from .023 to .025, one would display .023 and the other would say .025) rather than having to watch a constantly changing display that fluctuates between the number.   I am running labview 8.20 and using a NI Elvis to hook up to the tranducer.

 

Thanks for the assistance.

I assume you are taking the data in a loop... so use a shift register and concatenate the latest results onto the end of an array.  On the output of the concatenator, connect an Array Max and Min... and you're done.

Hi,

 

 in the comparison palette you will find a min/max function. Use it with a shift register to always keep the min value for the indicator (or max for the second)...

 

@Matt:

Why do you want to build an array when you just need the min/max value?
