Example 1 with JFreeChartEntity

use of org.jfree.chart.entity.JFreeChartEntity in project SIMVA-SoS by SESoS.

the class JFreeChartInfo method draw.

/**
 * Draws the chart on a Java 2D graphics device (such as the screen or a
 * printer).
 * <P>
 * This method is the focus of the entire JFreeChart library.
 *
 * @param g2  the graphics device.
 * @param chartArea  the area within which the chart should be drawn.
 * @param anchor  the anchor point (in Java2D space) for the chart
 *                (<code>null</code> permitted).
 * @param info  records info about the drawing (null means collect no info).
