Label Every Other Point In a Plot

Say I were to do a plot as such

scatter(x,y)

How would I label every other point. For example, if there were 7 points. How should I go about labeling 1,3,5,7? Would I use a for loop? Or check if each point is odd?

Thanks all.

See https://www.mathworks.com/help/matlab/creating_plots/create-line-plot-with-markers.html#bvcbmlx-1 -- plot() with 'MarkerIndices'

Provided, that is, by "label" you mean "put a marker"

If you mean put a text point, then

%data for demonstration
x = rand(1,7);
y = rand(1,7);

%the work
scatter(x,y)
hold on
text(x(1:2:end), y(1:2:end), string(1:2:length(x)).')
