[aothmani]

Hello everybody
I need your help. I have to variables X and Y. how can I representon a graph Y=f(X)?.

An XY graph? But that's just a guess, are there more details you can provide?

Hello
this is very shortly my work : I want to command to measurment instruments (Synthesizer and signals Generator  : HP 8341B and Spectrum Analyzer : HP 70700A, 70004A).

in the attachment you can find more details.
please verify this VI with me.
I want to represent "puissance" =f("fréquence) (look at the loop for) : How?
I have another question : how can I recuperate the graph of the spectrum which I recieve on my analyzer? in another words how can I get the same window of the  analyzer'screen on my front pannel?
thank you

Ok, this is much simpler. In this case the X-Axis values are a set increment which means you can use a simple waveform graph to present the data and use the graph's X-Scale.Multiplier property to set the scale increment. Several of the FFT operations (like Auto Power Spectrum.vi) have a df output that you can use to set the increment.
