      <itunes:summary>I don't think it's possible to do what you ask.  However, this might be an acceptable work-around:

restart;
with(Statistics):
PieChart([Wales = 40,  Unknown = 56, GB = 341, E = 237, RUS = 31, D = 93, F = 91,  IRL = 39, S = 35, Other = 244], color = orange .. green);

As you will see, I changed the order of some of your entries and substituted the international vehicle country identification letters for the country names. Hope this helps.

      <title>Pie Chart labels</title>
      <link>http://www.mapleprimes.com/questions/40921-Pie-Chart?ref=Feed:MaplePrimes:Pie Chart:Comments#answer75892</link>
      <itunes:summary>I'm not aware of ways to do this directly with a command but there are a couple things you can do with the drawing tools.  Use:

PieChart([England = 341, Spain = 237, Germany = 93, France = 91, Unknown = 56, Wales = 40, Ireland = 39, Sweden = 35, Russia = 31, Other = 244], color = orange .. green, captions = none);

Which will remove the labels completely.  Then you can either use the drawing tools to add the labels yourself (select the plot, click on the Drawing toolbar at the top left and use the Text("T") and line tools to add labels and arrows.  Use the Drawing Components palette to change the linestyle to an arrow.

Alternately, you can right-click on the plot, choose Plot&gt;Legend&gt;Show Legend and mark it up accordingly (double-click on the text to change them).  You might want to change your colours to be more easily differentiable in this case.

      <itunes:summary>It should be possible to "fix up" the pie chart after the fact, using Maple itself. The pie chart gets created as just another PLOT structure, and hence should be subject to programmatic manipulation.

For example,

restart:
with(Statistics):
p:=PieChart([Wales = 40, Unknown = 56, GB = 341, E = 237, RUS = 31, D = 93, F = 91, IRL = 39, S = 35, Other = 244], color = orange .. green):
newp:=subsindets(p,specfunc({list,identical("Wales")},TEXT),f-&gt;subsop([1][1]=[op(1,f)[1]+0.5,op(1,f)[2]],f)):
plots[display](newp);

It should be possible to construct a maple procedure that moves all the captions away from the centre and outside the unit circle. One could likely make such a procedure reusable, for other pie charts.

      <itunes:summary>The other way you could try to do this is to use the legend facility. Create the Pie chart without captions, then make the legend visible interactively and edit each of the legends to the string you want. This will only work in Maple 11 or later.
