Hi!
I have a plot (attached). I want to scale it so that x axis is in [kHz] . I don't only want to scale the axis but also the whole plot, so that it wil show the values present in [kHz].
Thanks in advance.

Multiply x data with 10^(-3), and calculate the corresponding y data, then plot.

Okay! And what if i have a matrix 20000x5000, which is a 2D fft from numerical model responses after chirp signal excitation and it gives me a plot of frequency vs wave-number in [Hz] vs [1/mm] and I want it to be in [kHz] vs [1/m]. Can I somehow multiply the values in the matrix ?
