The example should update the data without flicker. If you then set the
doublebuffer property to off, you should see the window flicker as the
new data updates the plot.

34.8 Guide

When writing code to generate GUIs you can very quickly get bogged
down in messy coding. For example, it is tedious to calculate the “posi-
tion” properties of the various elements so that they line up nicely. The
task of generating GUIs is made much easier with the matlab tool
guide. The name guide is short for Graphical User Interface Devel-
opment Environment. Guide is a GUIfor drawing GUIs. With it you
select uicontrols, position them with the mouse, align them with the
alignment tool, and set the properties with a graphical property editor.
Iused guide to produce most of the GUIexamples so far. When you
type guide at the matlab prompt, the current figure shows a grid in
the background, showing that it is now a guide-controlled figure, and
the guide control panel appears. Try typing guide now and you should
see the following control panel on your screen:

The four big buttons at the top of the control panel bring up four other
control panels. The listbox in the middle displays which figures are being
