Grafana X Zabbix - Graphics with different values.

Hello,
I’m sorry for my english.
I am using grafana to demonstrate the capacity planning of my servers.
I already have the screens developed in Zabbix. I made the integration between the tools and everything is ok. However, there is a difference between the values ​​presented in grafana and zabbix. I need to scale the graphs using the maximum line of processing the memory but the grafana does not present this line of representation, only the midline.

I need help solving this problem. In annex I send the graphs of both softwares and the query.

processor_graf processor_zabbix
config_grafana
