I haven't found anything on google solving my problem:
Whenever I try to make a pie chart with only one row containing a value greater than 0, calc hides the diagramm (so there is never a complete cake

These only happens on 2D pie charts. changing it to 3d makes it work. the 2d version also worked in OO 2.2.
I've attached an example, were the upper right diagramm gets empty in 2.3 and 2.3.1!
open in 2.2 and pressing F9 makes it work for 2.2...
