Visualizing numerical sensor data in a line chart

Dashboards & Visualizations

Hi,

As a total beginner (I've scrolled through the tutorial) I have imported a .csv file containing sensor data with the following format:

timestamp,signalName,signalValue

example)
2019-06-20 11:32:00.57, SIGNALGROUP01/AmbientTemp, 27.475

I think I've managed to import everything correctly and the signalValue appears to be located in a field called "0" (maybe this is the default field name?).

I'm able to search and list all the events using the following search:

host=LOGFILE SIGNALGROUP01/AmbientTemp 0="*"

Question:
How do I go about visualizing the AmbientTemp in a line plot? I have potentially tens of thousands of events with AmbientTemp in the file.

Thanks
