I want to calculate the directivity vs wavelength plot like this:

 

for a broadband dipole placed inside a pillar.

I had followed the example file but how do I get the plot w.r.t wavelength? Do you have any other code for this?

As you can see from the above link, the directivity is a function of the far field angles at a given frequency. The plot you showed might be either the max directivity at any direction, or at a specific direction. In both cases you will need first to calculate the directivity at each frequency.
