How am I supposed to get a plot from this code on WeSpice(NGspice) engine?

As stated many times. None of us use WeSpice. After seeing you struggle with WeSpice none of us will try that program.
If you asked the question about LTSpice then 30 people will answer. LT Spice = free.
There are experts on Spice here that use several types of spice.

40 years ago I used some programs that were not good. In those days:
".plot dc v(3) -i(vbias)" would plot negative. Try ".plot dc v(3) i(vbias)" or .plot dc v(3) +i(vbias)
In many old spice programs a (-) ahead a net name caused the plot to be inverted.

I think I found the problem. I was not using the .control and run command. Now it is ckear that why it was not working. But there is another problem now. Take a look at the screenshot,please.
