Example 1 with RenderingSource

use of org.jfree.chart.RenderingSource in project graphcode2vec by graphcode2vec.

the class AbstractCategoryItemRenderer method initialise.

/**
 * Initialises the renderer and returns a state object that will be used
 * for the remainder of the drawing process for a single chart.  The state
 * object allows for the fact that the renderer may be used simultaneously
 * by multiple threads (each thread will work with a separate state object).
 *
 * @param g2  the graphics device.
 * @param dataArea  the data area.
 * @param plot  the plot.
 * @param info  an object for returning information about the structure of
 *              the plot (<code>null</code> permitted).
 *
 * @return The renderer state.

Example 2 with RenderingSource

use of org.jfree.chart.RenderingSource in project graphcode2vec by graphcode2vec.

the class AbstractXYItemRenderer method initialise.

 * This method will be called before the first item is rendered, giving the
 * renderer an opportunity to initialise any state information it wants to
 * maintain.  The renderer can do nothing if it chooses.
 *
 * @param g2  the graphics device.
 * @param dataArea  the area inside the axes.
 * @param plot  the plot.
 * @param dataset  the dataset.
 * @param info  an optional info collection object to return data back to
 *              the caller.
 *
 * @return The renderer state (never <code>null</code>).
