This method is called by the XYPlot when it ends a pass through the (visible) items in a series.

Usage

From source file:org.openfaces.component.chart.impl.plots.XYPlotAdapter.java

private void renderItems(Graphics2D g2, Rectangle2D dataArea, PlotRenderingInfo info,
        CrosshairState crosshairState, XYDataset xyDataset, ValueAxis xValueAxis, ValueAxis yValueAxis,
        XYItemRenderer xyItemRenderer, XYItemRendererState state, int totalRendererPasses, int seriesIndex) {
    for (int currentPassIndex = 0; currentPassIndex < totalRendererPasses; currentPassIndex++) {
        if (xyDataset.getItemCount(seriesIndex) == 0) {
            return;
        }//www.  ja  va2  s.c  o m

        int firstItemIndex = 0;
        int lastItemIndex = xyDataset.getItemCount(seriesIndex) - 1;

        if (state.getProcessVisibleItemsOnly()) {
            final double xLowerBound = xValueAxis.getLowerBound();
            final double xUpperBound = xValueAxis.getUpperBound();
            int[] itemBounds = RendererUtilities.findLiveItems(xyDataset, seriesIndex, xLowerBound,
                    xUpperBound);
            firstItemIndex = itemBounds[0] - 1;
            if (firstItemIndex < 0) {
                firstItemIndex = 0;
            }
            final int lastBoundaryIndex = itemBounds[1] + 1;
            if (lastBoundaryIndex < lastItemIndex) {
                lastItemIndex = lastBoundaryIndex;
            }
        }

        state.startSeriesPass(xyDataset, seriesIndex, firstItemIndex, lastItemIndex, currentPassIndex,
                totalRendererPasses);

        for (int item = firstItemIndex; item <= lastItemIndex; item++) {
            xyItemRenderer.drawItem(g2, state, dataArea, info, this, xValueAxis, yValueAxis, xyDataset,
                    seriesIndex, item, crosshairState, currentPassIndex);
        }

        state.endSeriesPass(xyDataset, seriesIndex, firstItemIndex, lastItemIndex, currentPassIndex,
                totalRendererPasses);
    }
}
