Cannot seem to figure out time domain graphs

Hello

I am very new to learning electronics and I am slowly working through amazon signature collection online video course on modern electronics. I am trying to make a clamp diode, diode limiter, and diode shaper. However the time domain simulator for some reason does show the graphs I am expecting.

Can anyone explain what I have done wrong?

I have made the 3 circuits public, but would be grateful if anyone would be able to explain what I am doing wrong.

I have found Professor Wolfson's Circuits for diode 2 and 3. I will try directly compare. https://www.circuitlab.com/circuit/9t3rgb/l6-diode-clipper/ https://www.circuitlab.com/circuit/ddbs26/l6-diode-shaper/

I have gone through Prof Wolfson 2nd circuit, 2 things I changed were the 1st diode to match his one also put a ground under the triangle voltage source.

the 1st one I still am strugglling but i am going to leave this thread
