Hello i need to show with pspice plot the point-contact of diode.
this is the circuit and the values i need:

the right solution should look like this plot

but this is the plot i see

thx in advance!

I'm not too familiar with PSpice's equation plotting details, but I do notice that there is a difference in the format of the expressions that your diagrams show. Do you need the parentheses to make the order of operations clear?

im aware to this difference its not the case thx..
 
Okay. I noticed something else... The "good" plot has V(D1:1) on the x-axis. Your plot has V_V1. Presumably that means the good plot is plotting the other quantities against the diode junction voltage, whereas yours is plotting against the swept source voltage value.

You need to figure out how to place the diode voltage on the x-axis of your plot.

looks like you right!
thx..
 
yea, the man is right you just need to change your x-variable... go to plot->axis settings->x axis->axis variable and put v(d1:1).
