Cheshire Cat Computing

[quote="stevesh"]The way I was thinking of doing it was to have something like:

cdef:v1=ds0
cdef:v2=ds1,-1,*
area:v1
area:v2

which would fit in nicely with the current structure of the rtr_params and usr_params subroutines.[/quote]

Steve , this pertains to my post of "Plotting positive valued error counts as negative values" on 26-Mar-2008 .
I'll add this request to "routers.cgi : Feature Requests" as well .
How about creating a option called 'inverse' or something like that that will do the "...,-1,*" on both ds0 & ds1 ?
Then I can (somewhat) easily create a combine graph having the interface traffic showing on the '+' side of '0' & the interface error hit rate showing on the '-' side .
Sound reasonable ?

You could always just use 'Factor[xxxx]: -1' in your MRTG .cfg file instead - this will work with routers2 as it supports negative factors, I think (I might need to check this)

Fyi , router.cgi works just fine with factor[xxx]: -1 .
But if one uses "Working day average:" the coloration is only above the '0'(zero) line , tho .
thank you . Now I get to create a combined graph , change colors , .... this aught to be interesting ...

I think you've found a bug.... you win a cookie

It seems that the working day colouring (and the greyout colouring probably) go from 0 to +Inf and so if the graph is negitive then they dont colour the bottom half.

If I remember right (from a long time back) this was because a bug in RRDTool under Windows meant that if you specified to colour from -Inf to +Inf you in fact got nothing -- -Inf was treated as +Inf. Also, refering to -ve number when the line was only +ve messed up the axis (you had part of the graph -ve even though the line was always +ve).

This may be fixed now, so I might re-try it. Not sure about RRD 1.x compatibility though.
