Do you mean labeling individual data points in a plot? I can give you an example of that in the simplest possible Direct Graphics code: seed = 1L x = findgen(10) y = randomu(seed, 10) * 100.0 plot, x, y labels = ['JAN', 'FEB', 'MAR', 'APR', 'MAY', 'JUN' , 'JUL', 'AUG', 'SEP', 'OCT'] xyouts, x, y, labels, ALIGNMENT=0.5 James Jones
