Plotting only few indices over time series

Hi,

I wanted to highlighted with a different marker may be, over a plot only for a fewer indices over time series.

e.g. for a time series x having size(x) = 400 x 1

plot(x) first and highlight only set of indices y = [28,300,349,388,389] over the original curve.

I tried to find the solutions on mat exchange but couldn't. Any help would do please?

hello

my 2 cents suggestion :

n = 1:500;
x = n.*(1+rand(size(n))); 
ind = [28,300,349,388,389];
plot(n,x,'b',n(ind),x(ind),'dr','markersize',15);

Brilliant, thanks.
