When creating a pie chart, we are not offered the choice of the orientatio (clockwise/counter-clockwise) of the pie slices or donut regions; nor are we offered to set the initial angle. THis is despite the chart wizard having a "data series" section, and in the final orperties, there is a data-series option section in the Wizard - but it doesn't offer any of these options. Later, these settings don't appear on the sidebar anywhere. One could also argue that these are not quite data-series options, seeing how a pie or donut typically have just one "data series".
Charts have many attributes and I see no special need why the orientation needs to be present in the creation wizard. => WF
(In reply to Heiko Tietze from comment #1) > I see no special need why the orientation > needs to be present in the creation wizard. => WF The absence of these options from "data series" in chart creation suggests to the user it isn't a data series attribute, hence they don't go look for it in the data series options dialog later.
