    final SparklineParameters sparklineParameters = new SparklineParameters(rendererLabel.getWidth() - 1, rendererLabel.getHeight() - 1, Color.BLUE, background, Color.RED, Color.GREEN, null);

    SparklineParameters parameters = new SparklineParameters(200, 20, SparklineParameters.DEFAULT_LINE_COLOR, new Color(225, 255, 255), Color.RED, Color.GREEN);
    parameters.setHighlightTextColor(SparklineParameters.DEFAULT_TEXT_COLOR);
