100 seeking -> How on android phone line graph, the horizontal axis is time, vertical axis digital

For example, I have a set of data, hoping to draw a line graph, the horizontal axis represents time and the vertical axis represents the number of my money.

Example:
2013-2-1 50
2013-2-3 80
2013-3-5 90
2013-6-10 120
2013-6-20 40
2013-7-31 77

Want more data in accordance with the horizontal axis is time, vertical axis is expressed by the digital line graph, how to draw?

Time is mainly horizontal divergence, and put me confused lived. . .

Min Max draw the horizontal axis is calculated and then calculate the coordinates of each point does not have to

SimpleDateFormat sdf = new SimpleDateFormat ("yyyy-MM-dd"); 
Date start = sdf.parse ("2010-01-01"); 
Date now = sdf.parse ("2013-01-01"); 
long x = Math.abs ((start.getTime ()-now.getTime ()) / (24 * 60 * 60 * 1000)); 
System.out.println ("------>" + x);
