[Bug]: Histogram "sum" does not sum but counts instead

[vlebert]

What is the bug? (in English)

When I am showing an histogram with a sum concatenation, it actually displays the count of feature and not the sum of the targeted property.

Sum concatenations do work on scatter plots.

My data is a Spatialite Table

Here is a demonstration of that.

Steps to reproduce the issue

1. Load Spatialite data
2. Configure a Sum Histogram datavis

The Histogram is not the right graphic type. You have to use Bar diagram.
