Hi Steve, can you add a dividing line to the graphs at the value of zero when displaying negative values (such as temperature) just like you do for the mirrored graphs? See my screenshot with a black dividing line: hc_2013.01.28_12_16_47.jpg [ 179.6 KiB | Viewed 15831 times ] |

You mean, highlight the zero line? I notice that RRDTool doesnt do this. It would be an easy thing to add (HRULE:0:#000000) but might cause issues elsewhere? Will test. |

Yes, I mean highlighting the zero line. But of course only if there are any negative values present. In "normal" situations, the zero line must not be highlighted. |

I have a little update/question: In the summary page the graph has something like a very light line at zero. Where does this line come from?

The very light line is created by the RRDTool libraries by default. However it can get obscured by other data. |
