Mechanism for identifying row of matrix from a plot

Hi,

Consider the following scenario:

t = 1:5; X = randn(100,5); plot(t,X)

The resulting plot is comprised of 100 curves.

I'm trying to find an easy method for identifying the row index of X associated with a particular curve. The quantity of curves prevents me from using a legend to identify the row associated with each curve. I am willing to edit the plot. The editing tool does give you the precise values of any particular curve you select. I suppose I could use those values to go back and search through X to find the appropriate row index. I'm looking for something simpler than this.

Any suggestions?

Thank you.

Jason

I am not sure if this is a great idea, but it might help:

t = 1:5;
X = randn(100,5);
Y = [ (1:100)' ,  X  ];
plot([ 0, t ], Y);
