Pie Chart - Overview

The igPieChart is a charting control for rendering pie charts in HTML5 Web applications and sites. It uses the new HTML5 canvas tag to plot pie charts on web pages. The main features of igPieChart include legend, tooltips based on templates, controlling pie radius, controlling pie label position, start angle, sweep direction, exploded slices and distance from center for exploded slices. See the complete list of samples in the menu.
