 * *zooming the map to a combined minimum bounding box of all products in a dot
   group*: click on the dot group
 
+There are currently two ways how timeslider works connected to spatial filters:
+
+* Spatially un-aware: Always shows time distribution of all available products.
+* Spatially aware: Takes currently set spatial filter (or current map view) in account when displaying histograms. That way, time distribution of products over a specific area can be evaluated.

+In order to change between the modes, use the location switch in top right edge of the timeslider panel.
