AchartEngine Line Chart Xaxis Android

i am working achartengine on android and completed all works i have face one problem in line chart i mention the xaxis label but it's shows like 2,4,6,8,10,12 and so on with overlay with my xaxis label and i want to hide 2,4,6,8,10,12 labels in xaxis. if u don't understand see given below figure:

enter image description here

here is the full code:

public class ChartExample extends Activity {
