Plot radiating eletric field from isotropic antenna

I want to plot somehting like this. In the vertical axis is height and in the horizontal is distance. Color bar is in dB. How can I do this?

Hi,

I understand that you are looking out for the function to plot such graphs. 'contourf' function would do the trick for you to plot the above graph along with the colorbar. Simply, make a 2D matrix with values of the electric field corresponding to the respective height and distance parameters and feed it to the contourf function.
