Set chart text ANTIALIASING OFF

[xsistema]

Hi, I see no method to set chart text to ANTIALIASING OFF. Would it be possible to add this method?

When trying to force to override XChartPanel, this line still gets the priority..:
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

Tried many different ways - the only one way to get identical results to Java JLabel font painting is to use "TextLayout.draw()" method, not "getOutline() + fill()". So for chart title text I've changed the ChartTitle.java code to:

@Override
public void paint(Graphics2D g) {

  g.setFont(chart.getStyler().getChartTitleFont());

  if (!chart.getStyler().isChartTitleVisible() || chart.getTitle().length() == 0) {
    return;
  }

  Object oldHint = g.getRenderingHint(RenderingHints.KEY_ANTIALIASING);
  g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_OFF);

  // create rectangle first for sizing
  FontRenderContext frc = g.getFontRenderContext();

  TextLayout textLayout =
      new TextLayout(chart.getTitle(), chart.getStyler().getChartTitleFont(), frc);
  Rectangle2D textBounds = textLayout.getBounds();

  double xOffset = chart.getPlot().getBounds().getX(); // left edge
  double yOffset = chart.getStyler().getChartPadding();

  // title box
  if (chart.getStyler().isChartTitleBoxVisible()) {

    double chartTitleBoxWidth = chart.getPlot().getBounds().getWidth();
    double chartTitleBoxHeight =
        textBounds.getHeight() + 2 * chart.getStyler().getChartTitlePadding();
    g.setStroke(new BasicStroke(1, BasicStroke.CAP_BUTT, BasicStroke.JOIN_BEVEL));

    Shape rect =
        new Rectangle2D.Double(xOffset, yOffset, chartTitleBoxWidth, chartTitleBoxHeight);
    g.setColor(chart.getStyler().getChartTitleBoxBackgroundColor());
    g.fill(rect);
    g.setColor(chart.getStyler().getChartTitleBoxBorderColor());
    g.draw(rect);
  }

  // paint title
  xOffset =
      chart.getPlot().getBounds().getX()
          + (chart.getPlot().getBounds().getWidth() - textBounds.getWidth()) / 2.0;
  yOffset =
      chart.getStyler().getChartPadding()
          + textBounds.getHeight()
          + chart.getStyler().getChartTitlePadding();

  g.setColor(chart.getStyler().getChartFontColor());

  // ---- replaced getOutline()+fill() with TextLayout.draw() ----
  textLayout.draw(g, (float) xOffset, (float) yOffset);

  // compute bounds
  double width = 2 * chart.getStyler().getChartTitlePadding() + textBounds.getWidth();
  double height = 2 * chart.getStyler().getChartTitlePadding() + textBounds.getHeight();

  bounds =
      new Rectangle2D.Double(
          xOffset - chart.getStyler().getChartTitlePadding(),
          yOffset - textBounds.getHeight() - chart.getStyler().getChartTitlePadding(),
          width,
          height);

  g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, oldHint);
}


  /**
   * get the height of the chart title including the chart title padding
   *
   * @return a Rectangle2D defining the height of the chart title including the chart title padding
   */
  private Rectangle2D getBoundsHint() {

    if (chart.getStyler().isChartTitleVisible() && chart.getTitle().length() > 0) {

      TextLayout textLayout =
          new TextLayout(
              chart.getTitle(),
              chart.getStyler().getChartTitleFont(),
              new FontRenderContext(null, true, false));
      Rectangle2D rectangle = textLayout.getBounds();
      double width = 2 * chart.getStyler().getChartTitlePadding() + rectangle.getWidth();
      double height = 2 * chart.getStyler().getChartTitlePadding() + rectangle.getHeight();

      return new Rectangle2D.Double(
          Double.NaN, Double.NaN, width, height); // Double.NaN indicates not sure yet.
    } else {
      return new Rectangle2D
          .Double(); // Constructs a new Rectangle2D, initialized to location (0, 0) and size (0,
      // 0).
    }
  }

Y axis label painting:

                AffineTransform orig = g.getTransform();
                g.transform(AffineTransform.getRotateInstance(-Math.PI / 2, xOffset, yOffset));
                nonRotatedTextLayout.draw(g, xOffset, yOffset);
                g.setTransform(orig);

So now chart font is matched with an application font:
