realtime doesn't show correct data

[aprats]

Hi.

I've got a problem with realtime plugin. It works perfect but i got one problem related to SNR Upstream channels showing dB.
On the graphics it works perfect it show 30dB good, and the graph get its from snmp. As i know it gets 30.5 for example, but it read 305, then with a CDEF divide by 10, we got the real dB on the graphic.

But when i clic on realtime plugin in this kind of graphs (i got anothers about Cable modems count, and traffic (in&out) which works perfect)
The new popup with realtime shows me 3dB instead of 30dB.

It appears like realtime plugin do CDEF twice or something like this.

Can anyone help me?

I got cacti Version 0.8.8a
and realtime 0.5.2

Al the cacti works perfect, only this issue with realtime fails...

The question is: This cacti is a migration from another cacti server Version 0.8.7g with realtime 0.43 and it works perfect with realtime and shows 30dB instead 3dB

All the configuration and all is exactly because today i was veryfing it 10 hours.

maybe i touched something?
