GUI with Axes, Menu, and Toolbar

12-13

• The figure function creates the GUI figure.

• Setting the

MenuBar and Toolbar properties to none, prevents the standard

menu bar and toolbar from displaying.

• Setting the

HandleVisibility property to callback ensures that the figure

can be accessed only from within a GUI callback, and cannot be drawn into

or deleted from the command line.

• The

Color property defines the background color of the figure. In this case,

it is set to be the same as the default background color of

uicontrol objects,

such as the

Update push button. The factory default background color of

uicontrol objects is the system default and can vary from system to system.

This statement ensures that the figure’s background color matches the

background color of the components.

See the Figure Properties reference page for information about figure

properties and their default values.

The Axes

The following statement creates the axes.

hPlotAxes = axes(... % Axes for plotting the selected plot

'Parent', hMainFigure, ...

'Units', 'normalized', ...

'HandleVisibility','callback', ...

'Position',[0.11 0.13 0.80 0.67]);

• The axes function creates the axes. Setting the axes Parent property to

hMainFigure makes it a child of the main figure.

• Setting the

Units property to normalized ensures that the axes resizes

proportionately when the GUI is resized.

• The

Position property is a 4-element vector that specifies the location of the

axes within the figure and its size: [distance from left, distance from bottom,

height, width]. Because the units are normalized, all values are between 0

and 1.
