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.
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.
