Obviously your program contain a bug. E.g. it could be a script and define the needed values after the plotting. Then the 2nd run can access these values, but the first not - perhaps.

Please post the relevant part of your program, which reproduces the error. Otherwise it is absolutely impossible to guess, what the problem is.
