Detailed Description

Class to draw pie charts.

Just add one data set per piece (with one x-value). The x-Values should be the values used to calculate the pie or call addPie(). If the x-values are already percents, call also setPercents(true). Otherwise EChartPie calculates the percentages automatically.

To set the number format and precision, use setNumberFormat() and setNumberPrecision().
