I'm trying to do a simulation using Proteus for the NJFET Transistor …
But when simulating the Shockley's Transfer equation i get a wrong curve enter image description here

And here is graph's properties

You need to specify source 2 as drain current. At the moment, with only Vgate specified, it looks like you are plotting gate current against a base of gate voltage
