Hi,
  I guess the last problem i sorted out..now i have another one....

I have written a code for drawing a graph in the main class which
includes code for textfield and a button named plot.

My problem is i am getting the graph and textfield/button one at a
time.Both the codes are in the same main class ,wondering why am i not
getting them in the same frame both at the same time??

My code is given below.what do i change in the code to get the
text/button and graph field in the same frame??Thnx for the help.
