exponential scaling with percentage ratio displayed is broken for percentage

[human]

15:37 * math finds a bug in MRTG 15:40 <@math> IF you are using the percentage ratio thing between the IN and

OUT datas, AND you are using the EXPONENTIAL scale option to show more detail at the high scales (so 0-8 is crunched up but 8-12 is expanded, since your data always fits in values 9-11 for eg),

15:41 <@math> THEN the percentage scale for ratio of in:out on the right side

is also displayed as being exponential, but the data in it is actually non exponentially scaled.

15:41 <@math> my average ratio is 94% between my average power and peak power

readings,

15:41 <@math> but the ratio is always sitting in the 98.3 - 100% range in the

graph

15:41 <@math> which is wrong. if that was non exponential it would be 94% bang

on.

You may want to use rrdtool for better exponential plots.
