Hi,

see attached screenshot. More than 100% ;-)

To resolve this issue I would propose to add a setPercentagePrecision() method:

emun Precision
{
   PrecisionAuto, ///< %.3g
   Precision0,    ///< %.0f
   Precision1,    ///< %.1f
   Precision2,    ///< %.2f
   Precision3,    ///< %.3f
};

WPieChart::setPercentagePrecision(Precision prec)
{
   prec_ = prec;
}

WPieChart::labelText()
{
   ...
   double per = val / total * 100.0;
   switch(prec_) {
   case PrecisionAuto:
      snprintf(buf, sizeof(buf), "%.3g%%", pre);
      break;
   case Precision0:
      snprintf(buf, sizeof(buf), "%.0f%%", pre);
      break;
   case Precision1:
      snprintf(buf, sizeof(buf), "%.1f%%", pre);
      break;
      ....
   }
   ...
}

and using:

setPercentagePrecision(Precision2);

Any comments?
