Cacti ver.1.1.7 real-time setting and zoom feature issue

Dear Cacti user,
Good Day!

=================================================
i'm using CentOS Linux release 7.3.1611 (Core)
kernel is 3.10.0-514.16.1.el7.x86_64
spine 1.1.9
RRDtool 1.4.8
NET-SNMP version:  5.7.2
PHP 5.4.16 (cli) (built: Nov  6 2016 00:29:02)
mysql Ver 14.14 Distrib 5.7.18
Server version: Apache/2.4.6 (CentOS)
Latest Cacti ver. 1.1.9
=================================================

Currently i am using cacti 0.8.8h for production, it was nice and 
stable, i am happy with it 8) , and planning to upgrade to cacti ver.1 
in the near future.
so, i tested it first in dummy server doing new installation, installed 
cacti 1.1.9 first and then dump mysql database from old cacti (0.8.8h).

#My question is:
I figure out that some feature like real-time now embed to cacti, but is 
there any 'permission settings' to disable it for any specific user like 
on the old cacti version plugin ? so not all user can use it.

#Issue found :
I also found issue in the 'preview mode' , when i want to zoom in 
specific graph , the other graph also change/zoomed on the exact time 
and not found any log for this issue. picture attached.
FYI , This also happened on another cacti that migrated from cacti 0.8.8 
and installed on another OS like Ubuntu.

Your response will be appreciate.
Thank you for your kind attention and coordination.
