Hi there!

Please bear in mind that I am a complete IDL beginner so excuse any foolishness!

I have managed to plot an XY graph with data plots.

My problem lies with my next stage: I need to generate a line of gradient t^(-5/3) (then use oplot over my data).

I get the error 'Attempt to subscript T with I is out of range.' and when I type print,line I only get one value for my line...

Here is some code I was provided with as a guide, which I have modified slightly:

line=dblarr(9999)
n=1E-4
t=dblarr(9999)

for i=0,9999 do begin
t(i)=i
line=n*t(i)^(-5./3.)
endfor

I have used 9999 as 1E+5 was apparently too large, or something..

Any help would be much appreciated!!

Charlie
