        if (xyDataset.getItemCount(seriesIndex) == 0) {
            return;

        int firstItemIndex = 0;

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