Usage

From source file:edu.ucla.stat.SOCR.motionchart.MotionBubbleRenderer.java

/**
 * Draws the visual representation of a single data item.
 *
 * @param g2             the graphics device.
 * @param state          the renderer state.
 * @param dataArea       the area within which the data is being drawn.
 * @param info           collects information about the drawing.
 * @param plot           the plot (can be used to obtain standard color
 *                       information etc).
 * @param domainAxis     the domain (horizontal) axis.
 * @param rangeAxis      the range (vertical) axis.
 * @param dataset        the dataset (a {@link edu.ucla.stat.SOCR.motionchart.MotionDataSet} is expected).
 * @param series         the series index (zero-based).
 * @param item           the item index (zero-based).
 * @param crosshairState crosshair information for the plot
 *                       (<code>null</code> permitted).
 * @param pass           the pass index.
