Hi Bala,
There is no option to show cones like in the left panel of Fig 22, but for the electric field lines in the right panel, see command "measure fieldLines":

There is an example image in the Chimera Image Gallery:

Showing field lines requires already having an electrostatic potential map, which can be calculated in other programs outside of Chimera, or via Chimera with the PDB2PQR and APBS tools as in the last section of the "surface properties" image tutorial:

I hope this helps,
