How can I draw continuous curves in map plots?

Question

I am trying to make a line chart in the fleet, and I was wondering if continuous lines could be represented. I mean curves like y = ax ^ 2 + bx + c, or sin (x).

I already know that I can make an offer “for” and draw a curve like the calmness of short segments, but I would like to avoid this.

Is it possible? How can i do this? Thnx guys!
