How to visualize Duration Time of an Escalation Action in Log

Hi There

I have a work case which I am working on for Logs in Loki… I have an Escalation Log which i want to Display in a Grafic Vizualization in Grafana. I was able to visualize How frequently the Escalations run, by Grouping the Escalation Name. But I want to visualize either in a Timeseries or State Timeline Visualization what the Elapsed Time of Escalation is.

Because the Log is unstructured i had to create a Pattern Expression to pull out the needed information: Name of Escalation, Timestamp and Elapsed Time

Can anyone give me a hint how to do such a graph?
