I use a ucr time series data set.I extract some points based on a condition.The extracted points I need to mark in the original set.I use the plot function.

I don't know what "ucr" means, not do you say a thing useful to help us know what, specifically you have done nor what "a condition" is...POST CODE and DATA, not just words....

d = xlsread('FaceFour_TRAIN.xlsx');
plot(d);
hold on
idx = find(d>0.04);
pointsize = 20;
scatter(idx, d(idx), pointsize, 'b', '*')
hold off

s = d(1:1,2:end);
fa = movstd(s,20,1);
secarray = movstd(fa,20,1) ;
secidx = find(secarray>.04);
f = secarray(secidx);
[maxvals, maxidx] = maxk(f,10);
sidx = secidx(maxidx);
x = 1:length(s);
plot(x, s, 'b-', sidx, s(sidx), 'go')

d = xlsread('FaceFour_TRAIN.xlsx')
f=d(d>.04);
plot(d)
I need to mark the f in d and the d I need to represent like a single plot.How it possible please help me.
