Overlay Events on Line Graphs

I’d like to create a visualization that shows several types of data

  • a line graph of variable data like temperature
  • state of sensors when in a specific state like “Window is Open”
  • one-off events like “Fireplace Lit” (this has no end time)

Can this be done in Home Assistant or do I need to push the data to another system to do this type of thing?

Thanks!
