How can i draw curve fitting for panel data?

I want to draw curve fitting in other words I want draw fitted values(y_hat) vs dependent variable (x) but i have panel data two groups are "ID and Time(Year)
which are the data positions and time.

I use "np package" and done Nonparametric regression and obtained fitted value.
In my model both Id and Time are random. Then I estimate f(x,Id,Time). These are fitted values.

Now how can I draw curve fitting?

It's much easier to answer questions about code with code, so if you could include reprex (short for reproducible example), that would help us help you.

If you've never heard of a reprex before, you might want to start by reading the tidyverse.org help page.
