[Vega]Do not regenerate graph on auto-refreshing

Vega graph should auto-refresh its data. The simple way is to regenerate the whole graph every time new data becomes available. The more efficient ("proper") way would be to implement JS observables pattern - so when Vega requests Elastic Search data, return an object with .subscribe() instead of .then(). Vega will use that .subscribe function to provide a callback. This also requires a bit of upstream modification of the Vega's data loader code -- vega/vega#893

done in release v0.2.0 by simply regenerating the whole graph. This is not a very good solution (graph flashes and resets on every auto-refresh).

Reopening - renamed the bug to be about avoiding graph regeneration on refresh.

This issue is greater when you make a live map, for example: tracking of vessels, I can move by the map but I can't fit a zone because after auto-refresh the map come back to origin.

Is there any update on this issue?
