Hello @Stefan Schippers, do you know why is it that when trying to save the curves for a two circuits in different while, or those of one are saved or those of the other are saved, but it is not saved at the same time?

I think the best thing to do is save into 2 different files:

write curvas1.raw

...

...

write curvas2.raw

Yes, that's how I did it, but the problem is that if I show one, I can't show the other, or is there a way to call them at the same time?
