Hi Teddy,

Please try this:

enso = read_binary(file_which('elnino.dat'), data_type=4) ; 500 elts
time = findgen(n_elements(enso))
p_red = plot(time[0:299], enso[0:299], color='red')
p_blue = plot(time[300:*], enso[300:*], color='blue', /overplot)

I had to introduce the "x" parameter to make this work correctly.
