Show histogram is missing in 4.x

[sctse999]

Back in the days of 3.x, we are able to use donkey tubhist to produce a histogram regarding one or multiple tub. 4.x doesn't have this yet.

In the mobile app, we show this to the user to let them understand the distribution of the data they have collected.
