<div style="">You are using a fairly old version of the software -- MRTG is currently 2.16.4 and RRDTool is at 1.4.4 the last time I looked. Routers2 is at 2.21. The new versions have a lot more features.<br>
<br>
There is an expscale option in MRTG for exponential scale.<br>
<br>
You can use routers.cgi*LowerLimit[] to define where the Y axis starts if you dont want a zero-based y-axis.<br>
<br>
Unless you use the Routers2 extended option 'rigid' the y-axis will automatically expand to fit the data. So, you can make sure the 'unscaled' option is not set, the set routers.cgi*LowerLimit[]:69 and routers.cgi*UpperLimit[]:70 and the graph will expand
to show your data in the most detail possible arount 70F.<br>
<br>
With the latest Routers2 and RRDTool, you can even make a temperature graph display with a second axis showing the temperature in C (using ScaleShift)<br>

<p class="MsoNormal">Running mrtg V2.10.15, rrdtool V1.0.49 and routers2 V2.17. I am looking for a way to make my temperature graphs expanded scale.</p>
<p class="MsoNormal">They are normally around 70F +/- 4 or 5 degrees and I would like the graphs to start say around 55 and go to say 85 for full scale. Even better would for them to scale automagically to +/- 10F.</p>
<p class="MsoNormal">I did find reference to an expscale option, but it doesn’t seem to work for me. I get an unrecognized command error.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Can this be done?</p>
