[rrd-developers] Re: Strange Y labels in 1.2.9 with --alt-autoscale

[Kai Risku]

Hmm.. it seems like I forgot to mention that I actually am using the --alt-y-grid mode.
Without it, the labels work rather well, but the Y-range is not good enough.

I tried changing the sprintf format-strings in draw_horizontal_grid to %7.4f, and
then I actually saw how off the Y-gridlines where. I currently get the following
Y-grid labels: 68.732 G, 68.825 G, 68.918 G, 69.011 G, 69.104 G, 69.197 G.

So there is definitely something fishy going on here..

Regards,
    Kai

Hi Kay,

please try

--alt-y-grid mode ... this is for situations like this ...

cheers
