[rrd-users] rrdtool - features ... 2nd y-axis

Hello again,

I guess this is a special question for Tobias, however, any answer welcome.

I've searched the archives for features like a second y-axis and I found
that people have started working on this many years ago ...

Is there any particular reason it never made it into the released code?

I also found that the values in rrd seem to be stored as double float,
using 8 bytes each - however, using 64bit integer values would be more
precise (in terms of reproducable) and still enough for +/- 1e+19 ...
Counting bytes that would mean ~10 Exabytes ...

For some of my projects I would prefer having integer values, especially
if you use the rrd not only for grahing, but for logging as well.
Are there any attempts in that direction?

If I'm going to try to implement that change myself - as the author of
that tool, Tobias, how would estimate the amount of time needed?
I guess it will only affect the database part of it - not the graphing?

This is not meant to be any critism - the rrdtool is great as it is!

Many thanks for your feedback.
