LTspice: X-Axis Variable

In LTspice, is there a way to change the X-Axis variable?

In PSpice I can do a PWL simulation, then change the X-Axis variable (in Probe) to be a voltage within the circuit, thus displaying hysteresis.

I can't find a similar function in LTspice. ...Jim Thompson

Right click on the X-axis of the plot and enter the plotted quantity in the dialog box

I think what you want is to tag one node with a mouse down, leving the mouse down drag the pointer to another node, then release the mouse down. This will give you a chart of scale between those two points.

Unless you are talking something else?

Left-click on the X-axis, type the expression for your signal on the 'quantity plotted' line in the dialog that comes up, click OK.

How do I know what expression to type in? Thank you!

Doesn't work. I get Error : undefined variable. It used to work but stopped some time ago.

I am running IV.

Doesn't work. I get Error : undefined symbol.

It used to work but apparently stopped some time ago.

I and running IV.

Works for me in the latest versions of both IV and XVII. It has to be a circuit variable, e.g. I(R1).

Cheers
