        Parameters:
        g2 - the graphics device.
        state - the renderer state.
        dataArea - the area within which the data is being drawn.
        info - collects information about the drawing.
        plot - the plot (can be used to obtain standard color information etc).
        domainAxis - the domain (horizontal) axis.
        rangeAxis - the range (vertical) axis.
        dataset - the dataset (an XYZDataset is expected).
        series - the series index (zero-based).
        item - the item index (zero-based).
        crosshairState - crosshair information for the plot (null permitted).
        pass - the pass index.
      • getLegendItem

        obj - the object (null permitted).
        Returns:
        A boolean.
