When "Show triggers" option is set in a graph, description of triggers is added at bottom of graphs.
This is working in standalone graphs (Monitoring -> Graphs) but not when graph is included in a screen.

I have attached to screenshots:

• first one is standalone graph
• second is a screen containing same graph
  In second one, labels :
  Trigger: Packet loss higher than 40% on www [> 40]
  Trigger: Packet loss higher than 80% on www [> 80]
  Trigger: Ping failed on www [= 100]
  are missing at bottom of graph.
