LTspice: X-Axis Variable

Started by Jim Thompson January 25, 2016
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.

... Right click on the X-axis of the plot and enter the plotted quantity in the dialog box http://www.linear.com/solutions/1829 kevin

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? Jamie

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. Jeroen Belleman

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). <https://www.analog.com/en/technical-articles/ltspice-parametric-plots.html> Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510 http://electrooptical.net http://hobbs-eo.com

I got it! Thank you all so much
