Subject: libreoffice-calc: 3D elliptical diagram are NOT a correct way to represent data
Date: Fri, 23 Dec 2016 20:31:18 +0100

Dear Maintainer,

LibreOffice has the ability to create 3D circular diagrams, ie elliptical diagram.
In fact, this way to draw a diagram is false mathematically. The area of a sector in the front is bigger than the area of another sector of the same importance if it is placed right or left or in the back.
I know that some users might reclaim this feature but it’s a classical error in presenting data.
As far as LibreOffice is a quality office suite, it should not let its users create garbage graphics.
Just keep a line in the creation window that tells that this feature is in fact a bad idea.

I don't think this is the responsibility of the office suite... there are many ways data can be misrepresented with, either accidentally or on purpose.

One could argue the bar chart basing off from a bit below the smallest value by default is also an incorrect representation of data. (eg. a bar chart of values 100 / 102 / 104 / 106 will have 97 as the base value, not 0)

Right, let's close.
