Plot seven series

This example selects gem explicitly, so it does not depend on the active theme. Use it in R2025a or later for the colors shown above.

x = (0:0.1:2*pi)';
y = sin(x + (0:6)*pi/7);
figure
colororder(orderedcolors("gem"))
plot(x,y,"LineWidth",1.5)
xlabel("x")
ylabel("sin(x + phase)")
grid on
