Either Your minimum or your maximum are out of bounds for the array.
The array subscripts need to follow the c-like rules
0 <= minimum <= maximum
minimum <= maximum < n_elements(xlabels) - 1
One or more of the rules are being broken, generating the error.
You can either check the numbers before hand with "if" statements and ask
for a different number (keep asking using a "while" loop), or if you want
the default numbers to be 0:n_elements(xlabels) - 1 , you can force it
using > and <, e.g.
nx=n_elements(xlabels)
;as given, these lines have some redundancy, but are order independent.
minimum = minimum > 0 < maximum < (nx-1)
maximum = maximum > minimum > 0 < (nx -1)
;then carry on as before
gaussXrange=xlabels(minimum:maximum)
....
Chris.
