Example 11 with AxisState

use of org.jfree.chart.axis.AxisState in project SIMVA-SoS by SESoS.

the class CategoryPlot method draw.

/**
 * Draws the plot on a Java 2D graphics device (such as the screen or a
 * printer).
 * <P>
 * At your option, you may supply an instance of {@link PlotRenderingInfo}.
 * If you do, it will be populated with information about the drawing,
 * including various plot dimensions and tooltip info.
 *
 * @param g2  the graphics device.
 * @param area  the area within which the plot (including axes) should
 *              be drawn.
 * @param anchor  the anchor point (<code>null</code> permitted).
 * @param parentState  the state from the parent plot, if there is one.
 * @param state  collects info as the chart is drawn (possibly
 *               <code>null</code>).
