Bode/Nyquist plot.....

[don7]

Thanks, it's not working for me but I'll keep playing as I'm sure I'm doing something wrong ( calculator is brand new and I'm coming from a 48)

Seems that the check box disappears as soon as I run nyquist plot and graph is the same.

On home screen I enter:

C3:=-C2 (it returns {} or contains data.I'm guessing depending on if I executed bode previously)

In the symbol screen, I replace the C0 with C1 and C2 with C3 as well as check the box

I then evaluate the bode expression and get the same results as before. If I check back in the symbol I see the check box has cleared but C1/C3 remain.

I'll keep playing, thanks for help
