The ‘BorderLayout’ class developed for Java 1 is structured as a central plotting area surrounded by 4 panels, North, South, East and West.
The panels in turn can be subdivided by the ‘GridLayout’ class into equal areas in column/row format.
Within these areas, Buttons, Scrollbars, Text areas, Drop-down menus and Radio selection buttons can be placed for user interaction.
The central panel is usually reserved for plotting or drawing graphical data.
The size of the applet, X,Y in pixels, is determined by the settings in the .htm calling program. The plotted data needs to be constrained within the program set plot window by suitably addressing its pixel co-ordinates.
