That's a little difficult. My application allows the users to specify date range themselves by dragging a selection over the graph (just like in Cacti)<div>So I don't have a control on what the date range will be.</div>
<div>Anyway, would you mind telling us about your best practices for graph range/step calculation?</div><div><br></div><div>Thanks</div><div>RG</div><div><br><div class="gmail_quote">On Mon, May 21, 2012 at 10:42 AM, Simon Hobson <span dir="ltr"><<a href="mailto:linux@thehobsons.co.uk" target="_blank">linux@thehobsons.co.uk</a>></span> wrote:<br>

</div>You're best doing your own calcs anyway (and explicitly specify the<br>
resolution of data to be used) - it means you can optimise the<br>
graphs. If you just do (for example) "now-1month" to "now" then the<br>
graph may not be optimal. Pixels on the graph may not exactly match<br>
your data points, and so further data manipulation is needed. Also, I<br>
believe it's been vastly improved, but there used to be some<br>
situations where you could get the "wrong" consolidation used - a<br>
graph with lower resolution data than it should be.<br>
