@varnika I can only reproduce if the "X-axis scale" is set to "Ordinal" instead of "Timeseries".

We have some issues with MongoDB (and Druid) returning type/Instant instead of type/Date, which other databases do. We need to correctly handle this for those drivers, so they will work correctly everywhere in the GUI.
