Graphite infinite line

We are using Grafana to show graphite metrics.
We are also using graphite “events” to show our deployments within the graphs (red dashed line in the attached image).
Trying to add this metric in Grafana doesn’t work:
alias(color(dashed(drawAsInfinite(events(‘worker-deploy’))),‘red’), ‘deployments’)

is there an option to do this in grafana?

I found a solution, it’s called “Annotations” in Grafana.
Settings->Annotations->“Add new”
If you choose graphite as data source, you can add the event name and that’s it.
