for dynamic plots use GraphicalView rather then intent::

 public GraphicalView mChartView;

creat a xml::

then in ur code :

 LinearLayout layout = (LinearLayout) findViewById(R.id.graph);
 mChartView = ChartFactory.mChartView = ChartFactory.getLineChartView(getBaseContext(), dataset, renderer)
 layout.addView(mChartView); 

• After entering values you read from edit text fields right:

• then you are passing the new values to add in respective arraylists

• then you should call the code for linegraph again after adding new values and remember to clear series before reading arraylists (ie. dataset.clear();) ie. when line code function starts at beginning add dataset.clear(); because if u dont clear data will overlap and may through exception or line may look thick at old data ...

then call mChartView.repaint(); to refresh graph
