Steps to reproduce:

1. Use a graph with items and triggers (e.g. Memory usage (which actually shows the available memory thus renaming would be recommended) from Template OS Linux)
2. See that the trigger line is displayed in the graph.
3. Deselect Show triggers in the graph configuration so that only the items are displayed. 
4. Create a 2x1 screen.
5. Put the Memory usage graphs side by side in both cells with only one difference that for one element select it to be Dynamic item.

Result:

Trigger line is correctly not displayed for one graph but for the dynamic graph it is still displayed.

Same issue when tested on 3.0.12.

Expected:
Both graphs identical. 

Bonus issues:

1. Use a graph with Internal items for the test e.g. Data gathering process busy and select one to be dynamic. No graphs displayed at all. 
2. The graph is not clickable to expand in full. Regression from 3.0.12 where it works.
