Adding a Second Y-Axis

We see that the trace of I(R1) looks like it is constant at zero. This is because the numerical values of the current are 1,000 times smaller than those of the voltage. Delete the trace I(R1)  

T°nffcLthiS dlSplay problem we wi add a second y-axis. One y-axis will be used for the voltage trace and the second y-axis will be used for the current trace. The advantage of this arrangement is that the two y-axes can have different scales. To add another y-axis, select Plot and then Add Y Axis  

Note in the screen capture above that the axis we just added is selected. The next trace we add will be displayed using the selected axis, in this case, the new axis. Add the trace I(R1)  

Traces that are added are placed on the selected y-axis. Below, the symbol indicates that the second y-axis is selected  

Note that trace VfiO) is placed in the list of traces for y-axis 1.
