I have two matrices. One matrix is plotted and the other has information about each plot line.

Super simplified example:

`t = 0:.001:1;f = [10,20,30]; % information vector`

y = sin(2*pi*f.*t'); % output matrix

plot(t,y)

I would like to use the datatip to show the 'f' information along with the x,y coordinates. I am trying to follow the 'myupdatefcn' method using 'datacursormode', but I can't figure out which line (or column of the matrix) I am placing a datatip on.

Any help would be appreciated.
