Hi Imtiaz thanks for this. This is a very sensitive topic in the data visualization space, especially for those who are "experts" (aka Stephen Few, etc/) in visualization design. You are correct, this is done deliberately. If you are interested in learning more on this topic I can have one of our data visualization specialist chime in.
If you mean "not exactly" 3D - but you would like more depth, like drop shadows, thicker borders, etc - then please provide your ideas here and I will submit them to R &D for future consideration.
You are correct, more functionality around border etc, the softer touches I guess as oppose to full 3D.
I have worked on a number of solutions/components (Panorama, PowerBI, Dundas Charting etc) and many offer a range of functions to manipulate charts, either the full monty or just subtleness. It is the latter I am asking about.
Is this something perhaps QlikView offers rather than QS?
