Mutliple windows for an MDI child

I am writing a program that graph's some data. I need to be able
to display the data using two different methods. I would like to
display the data in two different windows. Changes in one window
should be automatically updated in the second window. I also need
to keep some of the data local to each window with no interaction
between the two windows. Does anyone have any suggestions on
how to do this? I am using Delphi 2.0 and Win '95.
