Add x=y line to the scatter plot

Hi, I have x and y data, where

x=[396.23;357.07;433.30;404.39;439.9;351.06;491.61;563.21;418.79;441.74;370.58;503.24;540.9;441.07;418.88;555.11;473.21;390.62];
y=[389.49;337.59;441.35;371.53;369.68;329.63;507.16;542.65;428.09;444.03;337.93;522.72;521.950;481.62;430.72;515.48;423.49;372.48];
scatter(x,y)
xlim([300 600])
ylim([300 600])
pbaspect([1 1 1])

How can I draw x=y line to this plot ? Is there any command to this ?

Thanks. It worked perfectly

Answer 2

[Sargondjani]

x = linspace(300,600,2);

y = x;

plot(x,y)

And you will need a hold command after the scatter command.
