View or Visualization for my watcher

[huantianad]

Hey just wanted to ask if it's possible to get some kinda simple visualization for my custom watcher. I have a watcher that simply checks if a specific window is open (not just active) and I want to see at a glance how long it's open for a specific day, which the timeline is not very helpful for. Is there a way I can reuse an existing watcher visualization?
