How to put text outside an xyplot?
...be simple, but I just couldn't figure out how to do it. How does this work?
Cheers,

...my specified variable "colors"
if possible, i.e. a single line segment starting from light gray and
ending with a dark gray.
Thanks very much in advance!

Simple plot loop
Trying to plot multiple lines from a simple matrix with headers (eight observations per column). I will be doing a number of these, with varying numbers of columns, and do not want to enter the header names for each one (I got frustrated and just wrote them out, which did work).
Data reads fine, first plot is fine, but when i use the code at the bottom for a for i loop it tells me that x and y
