Hi,

We've recently acquired a Keysight DAQ + Benchvue and while learning how the software works, I've been unable to find a way to plot custom functions on any of the available Graph Gadgets. Here's what I wanted:

I'm reading a thermocouple and a few 2-wire resistances and would want to plot them logarithmically like

log(R) / (T)

but I cannot find a way to do this. Is there support for custom display functions that are *not* simply linear (Mx + B) compensations?

If not, is there a way to integrate the DAQ with Labview so I can properly show the graphs I want?

Thank you!

The computed channel allows certain math operations to be done. But you'd probably be better off using Test Flow, which has a log function available in the math blocks. You can generate an XY chart in Test Flow and also export data to Excel and use its chart capabilities if you want.
