when analysing a signal which having noise after FFT, I need measure noise field level base on some spectrum range. When I add some conversion table(actually measured voltage being related to the magnetic field strengthen.)into this dynamic data which is after FFT, I use VI: scale and map directly, But It does't work. Does anyone have good idea?
for example:
the conversion table is drawn from one curve of the below figure:

You can use XY graph. Then, press Ctrl+H and point your cursor to XY graph to see how to plot data on it.
