How to measure/plot data, and logg it on the different time intervals?

[YePererva]

Hello!

I wonder how to implement different time intervals for plotting data on the chart/graph, and for logging? Using LabView 2015 SP1 .

For example: plot measurements every 1 second, but record only every 1 minute? Any examples / KB to read?

Thank you!

Have your loop iterate once per second to plot measurement data.

On each 60th iteration you also record data: you just need a case structure and Q&R (quotient&remainder)…

Would it be still possible to bound those intervals with inputs to change those on the lfy?

Yes.

I found storing timestamp of the previous log and comparing with desired time interval to work better and give some flexibility.

YES, this is the proper way to do something like this.
