I have four points that I want to plot on CIE diagram. I am using the following command:

plotChromaticity
hold on
scatter([x_1 x_2 x_3 x_4],[y_1 y_2 y_3 y_4])
hold off

Now I want to add legend for these four points. For example: 'red', 'blue', 'green', and 'yellow'.

How can I do that?

plotChromaticity

hold on

x = rand(1,4);

y=rand(1,4);

name =["red", "blue", "green", "yellow"]

name = 1×4 string array

"red" "blue" "green" "yellow"

for i=1:length(x)

hs(i) = scatter(x(i), y(i), 'DisplayName', name(i));

end

hold off

legend(hs)

Thank you so much. How can I remove data1 from the legend?

See the update above. Use handles of graphic objects.
