Designing a GUI

Before creating the actual GUI, it is important to decide what it is you want your GUI to do and how you want it to work. It is helpful to draw your GUI on paper and envision what the user sees and what actions the user takes.

Note   MATLAB software provides a selection of standard dialog boxes that you can create with a single function call. For information about these dialog boxes and the functions used to create them, see Predefined Dialog Boxes in the MATLAB Function Reference documentation.

The GUI used in this example contains an axes component that displays either a surface, mesh, or contour plot of data selected from the pop-up menu. The following picture shows a sketch that you might use as a starting point for the design.

A panel contains three push buttons that enable you to choose the type of plot you want. The pop-up menu contains three strings—peaks, membrane, and sinc, which correspond to MATLAB functions and generate data to plot. You can select the data to plot from this menu.
