@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
//super.onCreate(savedInstanceState);
Df.open();
x = Df.getidforgraph();
y = Df.getweightforgraph();//these two methods return int array fine
case might in the place where i call the method
Df.close();
}
public Intent getIntent(Context context){
/* int x[] = { 1,2,3,4,5,6,7,8,9,10 };// x values
int y[]= { 10,12,13,15,24,34,65,68,69,78 }; // y values s
if i use this it will works fine but if i call the methods it
will creches my app
*/

for(int i=0 ; i<x.length; i++ ){
series.add(x[i], y[i]);
