8 Programming a GUIDE UI
Note:Most MATLAB plotting functions clear the axes and reset a number of axes
properties, including the ButtonDownFcn, before plotting data. To create an interface
that lets the end user plot data interactively, consider providing a component such as
a push button to control plotting. Such components’ properties are unaffected by the
plotting functions. If you must use the axes ButtonDownFcn to plot data, then use
functions such as line, patch, and surface.
