Hi,
I have Crated a JFrame (Frame1) with 4 textfields and a button (by name GetBarchart).
My question is i will enter some values in 4 textfields and press the GetBarchart button it should display a new JFrame( say Frame2 ) and a Barchart with values taken form the 4 textfields should be displyed.
NOTE: I should get the BarChart displayed in Frame2 , NOT in Frame1.
