LTspice: what they don\\\'t want you to know ......

Hello, I am trying to plot the time derivative of a signal in LTspice, but I have run into two issues.

1st) I tried using the \"ddt(x)\" command as you suggested, but LTspice says it does not exist as a command.

2nd) Using D(x) i get a derivative, but it is not a smooth graph. Rather it looks like a bunch of small steps even when the parent function is smooth.

Can you help at all?
