Scaling law of quantum Hall plateau-to-plateau transition in single layer graphene is studied in a temperature range from 2 K to 50 K. We find that the scaling exponent is not universal. In a low temperature range, is about 0.13, while in a high temperature range, is about 0.33. The result indicates the dominance of long range scattering in graphene.
