Graph of Second-Order Circuit

currentvoltage

I know that a circuit is second-order circuit if there are two storage elements.
I used pspice to simulate RLC Parallel?

and I got this graphv_O (t) vs t>=0+

I feel like it is not correct.
Please tell me my mistake.

when there is only L present, the graph would look like this:

when there is only C present, the graph would look like this:

Change the voltage source to Vpulse, and the parameters in the Vpulse to:

V1=0
V2=10V
TD=1n
TR=1n
TF=1n
PW=10n
PER=10
