Usage

From source file:edu.jhuapl.graphs.jfreechart.CategoryGraphBarPainter.java

@Override

        RectangleEdge base) {//from w ww  . jav a  2  s .  c  o  m
    Paint itemPaint = itemProperty.get(row, column, Paint.class, renderer.getItemPaint(row, column),
            GraphSource.ITEM_COLOR);
    GradientPaintTransformer t = renderer.getGradientPaintTransformer();

    if (t != null && itemPaint instanceof GradientPaint) {
        itemPaint = t.transform((GradientPaint) itemPaint, bar);
    }

    g2.setPaint(itemPaint);
