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) ....
