libreoffice/chart2/source/controller/dialogs/res_DataLabel.cxx
Marco Cecchetti 9ed1dd01be tdf#90839: support for wrapped text in data labels and for centered data value 
Now in a pie chart the text of a label can be wrapped, the wrapping is
automatic and the maximum text width is fixed to almost half the pie
radius. This feature is used to import correctly the relative text
wrapping property provided by MSO.

Moreover the data value and percent value of a label are now centered
horizontally, respect with the label text.
