Hi,
First I assign a fixed value to the source that I want to sweep. I have set the value of V2 to 1V dc:
Then in the SIMULATE menu:
I select DC sweep. I have set V2 to step from 0 to 1V in 5mV increments.
I run the simulation.
When the simulation stops. If I [ALT] [LEFT CLICK] on a wire, I can plot the current in that connection.
(If I ever make to India, you owe me a cup of tea :D)
Regards,

If I use matched pair transistors does i have to use emitter resistors?
