Although I have seen many examples about doing this at ArcGIS Desktop, I am still trying to find a how to using QGIS. What I want to do is something like the image below.

    You could probably manipulate the 2.5D polygon style into doing that. – csk Dec 11 '19 at 17:04
  • @csk thanks for replying, I would appreciate if you could elaborate more on polygon manipulation. – Vinicivs Dec 12 '19 at 3:21

    It wouldn't be manipulating polygons, it would be manipulating the 2.5D polygon renderer, which is designed for displaying buildings. You would set up a 2.5d style, which creates a geometry generator style. Then you would need to make some serious changes to the geometry generator expression to introduce your data fields and add the bar graph. As far as I know it's never been done before, so it would be a lot of work in uncharted territory. I expect it would take at least two full days to accomplish. Good luck and please post a new question if you get partway into it and get stuck. – csk Dec 12 '19 at 17:08
  • @csk I want to thank you very much by your reply. It is exactly what I hope to find at stack. I'm still a beginner on QGIS and although it will take me much more than 2 days to learn and implement the solution, now I have a clear path to follow. – Vinicivs Dec 14 '19 at 1:56

    I'm glad it was helpful. I did something similar (but for a different purpose) here: gis.stackexchange.com/questions/337207/… As you can see it's not an easy approach, and I think your desired bar graph outcome will be even more complicated. It seems possible though. Please post your solution as an answer to your own question when you figure it out. – csk Dec 17 '19 at 16:51
