Drawing Average line on graphs

[markfree]

(Using Zabbix 5.0.7)

I created a widget with "Graph" type and wanted to see an average line on it acording to the Dashboard period selector.

As an example, the Graph bellow collects a performance mesure every 5m, but it shows not average.


By using a "Classic Graph" type I'm able to see the average according to the selected period but I can't draw an average line on it.


I was hoping to draw an average line but could not find that option with "Graph" type.

To remediate that behavior I created another item that calculates the average of the last 5 collected values and added it to the graph as shown bellow.

    avg("net.tcp.service.perf[https,,{$HTTPS.STATUS.PORT}]",25m)

Is there a better way to include an average line on a Graph?
Thanks

I realized another way to draw the average line on a graph.
We can use the aggregate function of the Graph widget pointing to the same item.

This way there's no need for another calculated item.

It actually works pretty good.
