I am trying to plot a spectrogram using Matlab. Basically what I need is to have: -time in the X axis -Velocity in Y axis -Intensity is the current (in pico Ampere)
Basically, I want to create a simliar plot as the one attached here.
Time is an array of 9000 elements Velocity is a matrix of 9000x128 elements Current is a matrix of 9000x1280 elements
I have a thermal velocity which I can also plot which is an array of 9000 elements.
Can anyone give sugggestion on how to plot it? I want to crate similar to the one below:
