How to graph diffrance of to values ??

Post by Arrow2005 »

I made 2 graps that check the value of signal and noice on a radio link.

if the signal is -88
and
the noice is -66

how do a make a graph that shows the gap ?

this value should be -22

would be happy for some help or pointers

Use a CDEF=a,b,- where a and b are related to the two data sources.
