How to align aChartEngine Chart properly in an Android layout?

I am trying to write a code to plot a graph using aChartengine in an Android layout.I am successfully plot the graph but i am facing issue to align the Graph in the layout within a certain ViewGroup.

MyCode :

MainActivity.java

public class MainActivity extends ActionBarActivity {

List<double[]> xValues;
List<double[]> yValues;
List<double[]> yValues1;

GraphicalView view;
MultipleTemperatureChart multiple;
RelativeLayout rlt;

@Override
protected void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);

    xValues = new ArrayList<double[]>();
    yValues = new ArrayList<double[]>();
    yValues1 = new ArrayList<double[]>();

    rlt = (RelativeLayout) findViewById(R.id.rlt);

    multiple = new MultipleTemperatureChart(this);

    int[] data = {143,144,145,137,156,146,158,139,144,143};

    double[] doubTime = new double[data.length];
    double[] doubNote = new double[data.length];
    double[] doubZero = new double[data.length];

    for(int i=0;i<data.length;i++){

        doubTime[i] = index;
        doubNote[i] = data[i];
        doubZero[i] = 0;

        index++;
    }

    xValues.add(doubTime);
    yValues.add(doubNote);
    yValues1.add(doubZero);     


    view =   multiple.execute(getApplicationContext(),xValues,yValues,yValues1);
    view.setBackgroundColor(Color.YELLOW);
    view.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, 400));

    rlt.addView(view);

}


}

activity_main.xml

<RelativeLayout 
xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4"
android:layout_width="match_parent"
android:layout_height="match_parent">


        <RelativeLayout 
                android:layout_width="match_parent"
                android:layout_height="500dp"
                android:orientation="vertical"
                android:background="#33cc00"
                android:id="@+id/rltParams">

            <RelativeLayout 
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:orientation="vertical"
                    android:id="@+id/rlt"/>

             <View 
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_below="@+id/rlt"
                    android:background="#cc4455"
                    android:id="@+id/view"/>

     </RelativeLayout>          

So these are the codes and screenshots of my issue. I want to plot the graph within the Green RelativeLayout and also the Red View need to come below the graph layout.

Please suggest me some solution or technique to plot the graphs in the layout properly.
