I’m trying to draw asymptotic Bode diagrams with Scilab, but I can’t get them like I’m used to: what I get is like steps in the phase diagrams, while I usually see them drawn with slopes (you can find examples here, where I originally posted the question and was redirected here; sorry for not inserting directly here the images, but as new user I can’t due to limitation of link and embedded elements: [Asymptotic Bode with Scilab - Stack Overflow](https://stackoverflow.com/questions/79595375/asymptotic-bode-with-scilab)).

with a slope instead of a step in the phase diagram.

Moreover, I’d need _only_ the asymptotic diagrams, without the real ones.

I tried looking at the manual for both `bode` and `bode_asymp` functions, and some tutorial on YouTube, but I wasn’t able to understand if it possible to do any of those things, drawing the asymptotic like in the second example, and having only the asymptotic.

Is this possible with SciLab?
