You are browsing a class reference for deprecated Version 2 of the JavaScript Charts.
Documentation for other versions: amCharts 4 (current) or amCharts 3.
Slice is an item of AmPieChart's chartData Array and holds all the information about the slice. When working with a pie chart, you do not create slices or change it's properties directly, instead you set array of data using dataProvider property. Consider properties of a Slice read-only - change values in chart's data provider if you need to.
