如何减少java.awt.font中的字母间距？

Question

I'm trying to make a graph with a numbered axis. However, I can't seem to decrease the spacing between these numbers. Here is the current code I am using to decrease the spacing between the numbers in my paintComponent method, but it doesn't seem to work:

super.paintComponent(g);

Map<TextAttribute, Object> attributes = new HashMap<TextAttribute, Object>();
attributes.put(TextAttribute.TRACKING, 0.5);

Font font = new Font("Monospaced", Font.PLAIN, 1);
Font font2 = font.deriveFont(attributes);

g.setFont(font2);

When the numbers are displayed, the space between them is the same as before.

I've tried reducing the 0.5 in the attributes.put() method, but it doesn't seem to reduce the spacing. I've also tried TextAttribute.KERNING and using TextAttribute.KERNING_ON , but that didn't work out either.

Any help is greatly appreciated!

Thanks :)

From TextAttribute.TRACKING JavaDoc :

Tracking values are typically between -0.1 and 0.3; values outside this range are generally not desireable.
