Display range of points(as an "i letter") in plot command

Hello all,

I have 4 sets of data that has 5 points per data set. If i want to graph this data set by showing a line on the largest and smallest value and a dot on the average value(a capital i shape) for eery set so the range of the values as well as the average can be seen in one plot, how can i dothis?

Thanks for your help!

Perhaps the stats toolbox boxplot would be what you need.

Exactly what i needed. Thanks!

Unfortunately, there is no marker in the shape of letter "I". Is the following close to what you want?

d=rand(4,5);
figure(1);hold on;
plot(max(d),'r:')
plot(min(d),'g--')
plot(mean(d),'b*')

Or use the errorbar() in a twisted way. Just specify an error matrix that is fit for your data but shows a proper size "I" shape.

d=rand(4,5);
figure(1);hold on;
plot(max(d),'r:')
plot(min(d),'g--')
E=0.05*ones(size(d,2),1);
errorbar(mean(d),E);
