Add Code for Components in C allbacks

Note For information about properties that you can set to control many

aspects of axes behavior and appearance, see “Axes Objects — Defining

Coordinate Systems for Graphs”.

If your GUI contains axes, you should make sure that the Command-line

accessibility option in the GUI Options dialog box is set to Callback (the

default). From the Layout Editor select Tools > GUI Options > Command

Line Accessibility: Callback. See “C om mand-Line Accessibility” on pa ge

5-11 for more information about how this option works.

Creating Subplots

Use the subplot function to create axes in a tiled pattern. If your

GUIDE-generated GUI contains components other than the subplots, the

subplots must be contained in a panel.

As an example, the following code uses the

subplot function to create an

axes w ith two subplots in the panel with

Tag property uipanel1.Thiscode

is part of the Plot push button

Callback callback. Each tim e you press the

Plot button, the code draws a line in each subplot.

a1 and a2 are the handles

of the subplots.

a1=subplot(2,1,1,'Parent',handles.uipan el1);

plot(a1,rand(1,10),'r');

a2=subplot(2,1,2,'Parent',handles.u ipanel1);

plot(a2,rand(1,10),'b');
