Is it possible to create a visualization that ignores the currently selected time range in a time based index?
Nope, I think there's a feature request for it.
I found the feature request - Local visualization time, independently from global dashboard time.
I need in the near future so I guess I will have to develop something similar.
I found this Visualization-specific time filter pull request. It seems like it can serve as a good starting point. In terms of UI, I want to do something different - I want to show a time range selection control on the visualization itself.
Any suggestions/ideas for the journey I am about to take?
I am a developer and I had to do this on a vis once (A custom visualization for a customer).
It's kind of hard to have a custom visualization "ignore" the filterManager. The workaround I found, was to actually create a copy of all the current filters, reload, and then set the filters again.
I can help out if you want.
