Need to Draw a Graph in AndroidPlot as shown in the image

Hi guys! I need to plot the below graph as it is in Android using AndroidPlot:

Target Graph: http://i.stack.imgur.com/vbMsl.png
My Current Graph: http://i.stack.imgur.com/TXQyn.png

I need exactly 4 grid line along x axis and the labels as show in the above image 

This my code:

    import java.text.DecimalFormat;
    import java.util.Arrays;
    import com.androidplot.series.XYSeries;
    import com.androidplot.ui.SizeLayoutType;
    import com.androidplot.ui.SizeMetrics;
    import com.androidplot.xy.BoundaryMode;
    import com.androidplot.xy.LineAndPointFormatter;
    import com.androidplot.xy.SimpleXYSeries;
    import com.androidplot.xy.XYPlot;
    import com.androidplot.xy.XYStepMode;
    import android.app.Activity;
    import android.graphics.Color;
    import android.os.Bundle;

    public class MultitouchAndroidplotActivity extends Activity 
    {

	@Override
    public void onCreate(Bundle savedInstanceState) 
	{
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
		MultitouchPlot multitouchPlot = (MultitouchPlot) findViewById(R.id.multitouchPlot);
		
        // Create two arrays of y-values to plot:
        Number[] series1Numbers = {90, 85, 80, 75, 50, 40};
		Number[] series2Numbers = {50, 50, 50, 50, 50, 50};
		
		//Adding a White Background setting Borders etc..
		multitouchPlot.setBorderStyle(XYPlot.BorderStyle.NONE, null, null);
		multitouchPlot.setPlotMargins(0, 0, 0, 0);
		multitouchPlot.setPlotPadding(0, 0, 0, 0);
		multitouchPlot.setGridPadding(0, 10, 5, 0);

		multitouchPlot.setBackgroundColor(Color.WHITE);

		multitouchPlot.getGraphWidget().setSize(new SizeMetrics(
	            0, SizeLayoutType.FILL,
	            0, SizeLayoutType.FILL));

		multitouchPlot.getGraphWidget().getBackgroundPaint().setColor(Color.WHITE);
		multitouchPlot.getGraphWidget().getGridBackgroundPaint().setColor(Color.WHITE);

		multitouchPlot.getGraphWidget().getDomainLabelPaint().setColor(Color.BLACK);
		multitouchPlot.getGraphWidget().getRangeLabelPaint().setColor(Color.BLACK);

		multitouchPlot.getGraphWidget().getDomainOriginLabelPaint().setColor(Color.BLACK);
		multitouchPlot.getGraphWidget().getDomainOriginLinePaint().setColor(Color.BLACK);
		multitouchPlot.getGraphWidget().getRangeOriginLinePaint().setColor(Color.BLACK);
	    
		 //Remove legend
		multitouchPlot.getLayoutManager().remove(multitouchPlot.getLegendWidget());
		multitouchPlot.getLayoutManager().remove(multitouchPlot.getDomainLabelWidget());
		multitouchPlot.getLayoutManager().remove(multitouchPlot.getRangeLabelWidget());
		multitouchPlot.getLayoutManager().remove(multitouchPlot.getTitleWidget());

		//Domain
        multitouchPlot.setDomainStep(XYStepMode.INCREMENT_BY_VAL, 1);
        // get rid of the decimal place on the display:
        multitouchPlot.setDomainValueFormat(new DecimalFormat("#"));
        

        // Reduce the number of Domain labels
        //multitouchPlot.setTicksPerDomainLabel(3);
        
        //Range
        multitouchPlot.setRangeStep(XYStepMode.INCREMENT_BY_VAL, 10);
        // get rid of the decimal place on the display:
        multitouchPlot.setRangeValueFormat(new DecimalFormat("#"));
        //multitouchPlot.setRangeValueFormat(new DecimalFormat("0"));
        
        // Reduce the number of range labels
        //multitouchPlot.setTicksPerRangeLabel(3);

        // By default, AndroidPlot displays developer guides to aid in laying out your plot.
        // To get rid of them call disableAllMarkup():
        multitouchPlot.disableAllMarkup();
        
        //Setting up fix Boundaries for x and y
        multitouchPlot.setRangeBoundaries(0, 100, BoundaryMode.GROW);
		multitouchPlot.setDomainBoundaries(0, 5, BoundaryMode.GROW);
		
		// Turn the above arrays into XYSeries:
        XYSeries series1 = new SimpleXYSeries(
                Arrays.asList(series1Numbers),          // SimpleXYSeries takes a List so turn our array into a List
                SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, // Y_VALS_ONLY means use the element index as the x value
                "Obw—d brzucha");                       // Set the display title of the series

		// Same as above, for series2
        XYSeries series2 = new SimpleXYSeries(Arrays.asList(series2Numbers), 
        		SimpleXYSeries.ArrayFormat.Y_VALS_ONLY,
                "Series2");
       
     // Create a formatter to use for drawing a series using LineAndPointRenderer:
        LineAndPointFormatter series1Format = new LineAndPointFormatter(
                Color.rgb(29, 95, 155),                   // line color
                Color.rgb(29, 95, 155),                   // point color
                Color.rgb(210,223,235));              // fill color (optional)
        
        
        // Add series1 to the xyplot:
        multitouchPlot.addSeries(series1, series1Format);

        // Same as above, with series2:
        multitouchPlot.addSeries(series2, new LineAndPointFormatter(
        		Color.rgb(20, 160, 229), 
        		Color.rgb(29, 95, 155), 
        		null));

        
    
    }
}
