I want to plot time vs frequency as x and y axis , but also a third parameter that is specified by the intensity of plot at (x, y) rather (time, frequency) point . [Actually , instead of going up with third axis in 3D visualisation , I want something like a 2D plot , with amplitude of third axis governed by the intensity(color) value at (x,y) ] . Can you please suggest me something similar that I am looking for ! These plots are actually called dymanical spectrum .
PS : I am plotting in python offline . I have gone through https://plot.ly/python/ , but still I am not sure which will serve my purpose .
Please suggest something that will help me accomplish the above
