See graph type in the field area

[PaulPoulain]

When you create a graph, the metrics shows the aggregation, but not the graph type:

It would be nice to have the icon close to the aggregation

Bonus: change the aggregation to have an icon or a single letter with a hint/helpbox/hover (ie R/C/D for Raw / Count / count Distinct), to avoid a too long area:

Maybe a single letter is too short (and I forgot Max/Min/Avg), so what about 3 letters (Raw / Cnt / Dis), still with a hint
