private void configureRenderer(MsSpectrumDataSet dataset, int datasetIndex) {

    final MsSpectrumType renderingType = dataset.getRenderingType();

    // Set color
    Color baseColor = dataset.getColor();
    newRenderer.setBasePaint(JavaFXUtil.convertColorToAWT(baseColor));

    // Set label generator
    XYItemLabelGenerator intelligentLabelGenerator = new IntelligentItemLabelGenerator(chartNode, 100, dataset);
    newRenderer.setBaseItemLabelGenerator(intelligentLabelGenerator);
    newRenderer.setBaseItemLabelPaint(JavaFXUtil.convertColorToAWT(labelsColor));

    // Set tooltip generator
    newRenderer.setBaseToolTipGenerator(dataset);
