Hopefully some of you can explain that behavior to me. The main issue is that it seems like the value which is saved into the RRD (which i see as last_ds) is not plotted, instead a consolidated (seems to me like that) value is plotted which is nearly like original one but not exactly. I am aware of the consolidation functions, we are saving AVERAGE and LAST values in to the RRD and i am printing the LAST value as a text below the graph. </div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><br></div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">I suggest that the graphing command is wrong and therefore actual last measured value isn't plotted? Following is an example. The measured value is 11.87, i can see it in my rrd but a slightly lower value (10.87) is plotted.</div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;
