I'm a QGIS-user and I'm looking for a way to add a frequency histogram in the print composer. The aim of it would be to visualize the distribution of values around the defined class borders of a given layer.
Considering QGIS can load such charts for graduated layers (properties > style > histogram), I thought it would be interesting to import them straight into a project's print composer. 
Does anyone have ever found a proper way to have this done ? I've come across similar topics, like this one How to create a histogram legend in QGIS print composer? … But in my case the main interest would be to have this fixed quickly and automatically, as this specific kind of chart can already be generated by the program.

This is currently not possible.
There is a related feature request to provide an export for the vector classification histogram.
