X Axis Label Question

Hi,
 String[] xAxisLabels = {"1995", 
		"1996", "1997", "1998", "1999", 
		"2000", "2001", "2002", "2003", "2004"};

 double[][] data = new double[][]{{1500, 6880, 4510, 2600, 
		1200, 1580, 8000, 4555, 4000, 6120}};

I can use  setNumItems method to limit the number labels in the Y-axis
For example, I want to display only 1996 and 1997 in x-axis. How can I do
that in X-axis?

Thank you very much.
