Thanks it is working now.

I use Rxstring directly in both methods.Can you give me link for System.Action<> ?

@Ralf Meier ,I displayed all data on chart at once ,then I hide the form using minimize button.After some period when I maximize the form,Chart Area was appearing in white color.After two and three seconds, it comes to normal condition, display its data.

I am working with winform application using C#.I want to read a txt file( size not fix it can be 2GB) and after parsing lines , save parse data on temporary location because ,I will be used that data for other task. what will be best solution to save parse data ?

I have tested two solutions:

1)datatable but it takes cache memory which is hanging application for further task.
2)Access db,but it is slow process, because every time we call ExecuteNonQuery() after parsing line.
