Thanks for the quick reply!<br><br>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.<br>

</div></div>the step is not necessarily unifor as far as the input data is<br>
concerned ... the data gets re-sampled inside rrdgraph prior to<br>
drawing ...<br>
<br>
what problem are you tring to solve ?<br>
