Hello
I have univariate variables (ojoru) and I want the matlab plot to shows xxxxx above the set threshold on the y axis
Please find my code below but there is an issue with it
y=ojoru;
n=length(ojoru);
x=zeros(1,n);
for k=1:n
if y(k) > 3
c = 'r*';
else
c = 'b';
end
end
disp (plot(y, c));
hold on
I will appreciate it If I get a solution for this

Draw the complete data once with 'b'. Then "hold on". Then draw the same data again with 'r*' and with
'MarkerIndices', find(y>3)
