How to draw line chart in android phone? -

I have a set of data I want to draw a line chart horizontal axis for time and vertical axis The amount is. 

  2013-2-1 50 2013-2-3 80 2013-3-5 90 2013-6-10 120 2013 -6-20 40 2013-7-31 77   
 Like the above data, there is horizontal time and vertical axis number. How to use this line chart? I confuse horizontal time. It's different.
