Steps to reproduce:

1. We collect network device parameters in the following format and upload to ZABBIX server (trapper):
    
   "200.200.5.32" FortyGigE1-7-1-13_state 1
   "200.200.5.32" FortyGigE1-7-1-14_state 1
   "200.200.5.32" FortyGigE1-7-1-15_state 1
   "200.200.5.32" FortyGigE1-7-1-16_state 1
   .......
    Corresponding to the host,item key and item value respectively.Then i can define the item key in the template

 
Now there is a requirement. I want to write another script to pass the user macros:
 
"200.200.5.32"  {$FortyGigE1-7-1-13}  FortyGigE1-7-1-13(describe xx13)
"200.200.5.32"  {$FortyGigE1-7-1-14}  FortyGigE1-7-1-14(describe xx14)
"200.200.5.32"  {$FortyGigE1-7-1-15}  FortyGigE1-7-1-15(describe xx15)
Then I can use the user macros to define the item key（support already）, and more importantly, I can define the graphs name（current not support）：

Result:

But the problem is that I can't use macros to define graphic names：

user macros can collect data in item items, but not in custom graphs。

Expected:

user macros support custom graphs

thank you very much.
