achartengine를 이용해 그래프를 구현하고 있습니다...

구글링을 통해 라이브러리도 다운받고, 소스도 찾아보고해서 그래프는 구현이 되었는데...


 이 그래프를 예제에 나와있는 Intent가 아니라 LinearLayout에 addview로 추가하려니 잘 안됩니다..

StatsLineChart.java

 public class StatsLineChart extends AbstractDemoChart {
          ....
	  public GraphicalView execute(Context context){
		  String[] titles = new String[] { "Graph A","Graph B" };
		  List<double[]> dates = new ArrayList<double[]>();
		  List<double[]> values = new ArrayList<double[]>();
		  int length = titles.length;
		  double[] dateValues = new double[] { 1,2,3,4,5,6,7,8,9,10,11,12};
		  dates.add(dateValues);
 		 dates.add(dateValues);
		  values.add(new double[] { 1, 2, 3, 4, 5, 7, 8, 9, 10, 10.5, 5, 9});
		  values.add(new double[] { 3,10, 5, 8, 7, 7, 2, 10, 5, 11,  10, 11});
		  int[] colors = new int[] { Color.RED,Color.GREEN };
		  PointStyle[] styles = new PointStyle[] { PointStyle.CIRCLE,PointStyle.DIAMOND };
		  XYMultipleSeriesRenderer renderer = buildRenderer(colors, styles);
		  setChartSettings(renderer, "2012 년", "Date", "", 1,12, 0, 12, Color.GREEN, Color.RED);
		  renderer.setXLabels(13);
		  renderer.setYLabels(10);

		  return ChartFactory.getLineChartView(context, buildDateDataset(titles, dates, values), renderer);
	}
}


GraphDemoActivity.java

 public class GraphDemoActivity extends Activity {
	private LinearLayout linear_chart;
	public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        setContentView(R.layout.main);
		linear_chart = (LinearLayout)findViewById(R.id.linear_statis);
		GraphicalView view = new HappyStatsChart().execute(this);
		linear_chart.removeAllViews();
		linear_chart.addView(view, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
		view.repaint();
	}

실행시켜보면 빈화면만 뜹니다.

main.xml에 LinearLayout하나만 뒀을 때는 정상적인 결과가 나옵니다..

addview할 때 잘못된 것같긴 한데.... 

아시는 분 답변 부탁합니다....
