I am not quite clear what you are asking for.
For time series data the Time Picker in Top Right sets the time range for the visualization and / or dashboard.
Can you explain in a little more detail what you are looking for.
I want to put a visualization on a Dashboard where the dashboard time range (Time Picker Top Right) is last 2 weeks but for a particular visualization I only want the last 24 hours.
Depending on what you are trying to accomplish you can save the Time Picker either relative or absolute as part of the visualization...
CORRECTION : Today on a dashboard you CAN set a different timepicker for each visualization See Below
BTW Have you tried Lens yet for visualizations?
