Interval plot in matlab

Hi there, can I plot an interval plot in matlab ? I have a repeated data, let's say:

t = [1 2 3 1 2 3 1 2 3 1 2 3 1 2 3] -> 3 time points, repeated for 5 measurements

y = [500 600 800 300 400 600 100 400 600 200 400 600 200 500 700] -> 3 value, for 5 repeated measurements

now, if I invoke this command:

scatter(t,y)

it will produce a close result for what I need, but I do not want the scatter dot, instead I want an interval plot for each measurement. Is there any way to do this?

Thanks

Interval plot -- is that like a box plot?

[CVR]

yes, but only with a line, not a box. It will show you the min and max value of your data
