Thanks for the quick reply! I want to display the resolution of the graphed data to the user. Since the data is resampled (by fetch?) I don't know the resolution. According to the fetch documentation "the fetch function is normally used internally by the graph function to get data from RRDs", so i guess the "step size" or resolution is known to the graph(v) function but not returned.
