Custom font bug in LogAxis?

[nick13]

Hi, There appears to be a bug when using custom fonts in a LogAxis:

Font font = new Font("Palatino", Font.BOLD, 18);
LogAxis axis = new LogAxis("Y Axis");
axis.setLabelFont(font);
axis.setTickLabelFont(font);
axis.setNumberFormatOverride(new DecimalFormat("0.000"));

If you comment out that last statement (setNumberFormatOverride), the custom font (Palatino) renders correctly. Also renders correctly if you use a NumberAxis. But as soon as you override the number format, the axis renders with the default font.

Seems to be an issue in all recent versions of JFreeChart.

Thoughts?

Looks like a bug and, in fact, someone already reported it before:

https://github.com/jfree/jfreechart/issues/98

I think the fix is to change the LogAxis.createTickLabel() method to start like this:

Code: Select all

    protected AttributedString createTickLabel(double value) {
        if (this.numberFormatOverride != null) {
            String text = this.numberFormatOverride.format(value);
            AttributedString as = new AttributedString(text);
            as.addAttribute(TextAttribute.FONT, getTickLabelFont());
            return as;
        } else {
