Problem with adding legend?

Hello,
My data are aranged by days and for each day I plot several trial in the same color. I would like my legend to be per day only! That is, say I plotted 5 trials for day 1 and 3 trials for day 2, then my legend should be composed of TWO LINES ONLY, one for DAY1 and one for DAY2. Currently, the legend creates a number of lines iddentical to the number of lines in the plot. Does anyone know how I can change to the way of presentation described above?
Thank you.

Yes, pass the array of handles of the selected lines as the first argument to LEGEND.

If I am understanding correctly, you can solve the problem very easily.

Just plot 1 trial of day1 and then a trial of day 2. Now put your legend. And then continue and finish your drawings. That's it.

Best.

Didn't understand. Can you please give an example for how you "pass the array of handles of the selected lines as the first argument to LEGEND" ???
Thank you :)

h=plot(rand(10,5))
legend(h([1 end]), 'first','last')
