    assertEquals(5D, scale.getMajorTickIncrement());
    assertEquals(2, scale.getMinorTickCount());

    assertEquals(Font.ITALIC | Font.BOLD, scale.getTickLabelFont().getStyle());
    // had trouble getting a font comparison to work without breaking it down into size, style, and name
    assertEquals("Monospaced", scale.getTickLabelFont().getName()); //$NON-NLS-1$

    assertEquals(5F, ((BasicStroke) scale.getMajorTickStroke()).getLineWidth());
