When creating a pie chart in Excel then pasting into Powerpoint, I have
trouble getting the data lablels to look ok. Often times the font is so
small it can't be read. When you increase the font size, often a the label
such as "October Sales" would be pushed to 2 lines with "October Sa" on the
first line. When you select the label, a box appears around the words, but
it can not be resized, to get the label back to one line. My work around
has been to delete all the label info and leader lines and then to retype the
info using drawing/text boxes. Problem is the text boxes are not related to
the pie chart and any changes to the pie chart data is not carried over to
the new text boxes.

Hope this all makes sense.
