Class Canvas

java.lang.Object

com.codename1.charts.compat.Canvas

public class Canvas
extends Object

An internal compatibility class for use by the Charts library. Since the library was ported from an Android library, it made use of Canvas and Paint, so rather than rewriting all of this, we added a Canvas and Paint compatibility layer.
