Chart

Employment/Purpose

A chart is used to show a set of data as a graph. It helps users to judge things with a snapshot. To use a chart component , developers must prepare a ChartModel and a ChartEngine. Developers also set proper chart type, and the threeD (3D) attribute to draw proper chart. The model and type must match to each other; or the result is unpredictable. The 3D chart is not supported on all chart type.
