How to draw estimated kernel densities of two series in one figure?

I have two series of wage in 2007 and 2020. I would like to draw the estimated kernel densities of these series in on graph. How can I plot it? I have drawn estimated kernel densities, respectively. But I want to draw these in one figure.

Here are two different methods

N = 50;
x1 = randn(N,1);
x2 = randn(N,1) + 1;

[f1,xi1] = ksdensity(x1);
[f2,xi2] = ksdensity(x2);

% Method 1
figure
plot(xi1,f1,"r-",xi2,f2,"g-")

% Method 2
figure
hold on
plot(xi1,f1,"r-")
plot(xi2,f2,"g-")

If I were doing this, I would probably do the KS density estimations at the same x points, rather than letting the default select the locations.
