MATLAB: I have a function which plot a certain graph. How should I code this so that the function will not deliberately plot in a figure but in the axes of the gui instead

figure

You need to tell that plotting command which axes to use, by providing the axes handle. How to do this depends on the plotting command that you are using (you did not state this in your question), but as an example plot accepts the axes handles as the first input argument (here fgh is the figure/tab/panel handle):

axh = axes(fgh,...)
plot(axh,...)

For some other functions you will need to set the 'parent' property, read their help pages and property pages to know the required syntax:

somefun(...,'Parent',axh)

If you want to write reliable code than always obtain and use explicit graphics handles for all graphics functions and operations. Never assume that the current figure/axes/line/patch/... are the ones that you code needs to access. Read more here:

MATLAB: How to use the tag/name/handle of a axes rather than gca

You can use findobj to find axes with a given tag (as far as I know, there's no name property for axes)

hax = findobj(groot, 'Type', 'axes', 'Tag', yourtag);

But best would be to store in a variable the handle of the axes when you create it, avoiding having to search for it entirely.

MATLAB: How to make the GUI plot into an axes within the GUI figure rather than inside of a new figure in MATLAB

This change has been incorporated into the documentation in MATLAB 7.1 (R14SP3). For previous releases, read below for any additional information:

There are 2 factors in each of these situations:

1. The availability (HandleVisibility) of the axes to be plotted in.

2. The selection of the current axes (where the plot will be created).

An explanation of how to set the properties of the figure/axes properly and how to make sure that the proper axes are the current set of axes is listed for these situations below. Note that there are also other methods for indicating in which axes you want to plot:

1. Certain plotting routines allow you to specify the axes to plot in by including the Parent property-name/property-value pair as an input, such as the low-level plotting commands like LINE and SURFACE.

2. Other routines won't allow you to specify the Parent axes of the graphics objects as an input, i.e. high level plotting commands like STEM. You can, however, set the Parent of the graphics objects after they are created:

p=stem(1:10);
set(p,'Parent', axes_handle)

(Where axes_handle is the handle of the axes in which you want the object to appear.) One problem with this method is that it may cause the creation of a new figure or set of axes, which will still exist after the object's Parent is changed. In this case, you can use the DELETE function to remove the extra figure/axes.

Situation #1: Inside the GUI's callbacks

**********************************************

Use the AXES command to select the set of axes that you want to plot in, before executing the plotting command. Since the axes should have already been added to the GUI in GUIDE, a handle for it should have been included in the 'handles' structure of the GUI. If the Tag property value for the axes you want to plot to is 'axes1', then its handle is stored as 'handles.axes1'. Use the following to make it the current set of axes for plotting.

axes(handles.axes1)

You will also need to make sure that the figure's and axes' handles are 'visible' to the Callback functions. This will make them available for plotting commands. Set their HandleVisibility properties to 'callback'. You should also check the GUI's Command-line accessibility option:

1. Choose GUI Options (R13) or Application Options (R12.1/R12.0) from the Tools menu of GUIDE.

2. In the Command-line accessiblity pulldown menu, select Callback.

3. Click OK.

Situation #2: From the Command Window

************************************************

By default, GUI's have their Handle Visibility set to Callback, so they won't be affected by commands from the MATLAB Command Window. There are 2 ways to work around this:

1. Setting the figure's and axes' HandleVisibility property to 'on'.

2. Setting the root's ShowHiddenHandles property to 'on'.

The first method will affect only that GUI. It will make the GUI accessible from the command line, like standard figures. The second method will apply to all GUIs/figures that are open, in which case there may be some confusion regarding to which axes the plotting commands will be applied. In either case you should use the AXES command to set the current axes. If you have multiple axes, you may need to use another command to determine the handle for the axes that you want to plot into. You can use the FINDOBJ function to locate a particular object whose properties match certain property/value pairs. For example the following will return a variable 'h' that contains the handle(s) for any object(s) that are a Type 'axes' and have a Tag 'axes1'.

h=findobj('Type','axes','Tag','axes1');

It is possible to have more than one object that matches these properties, so you should make sure that you either set distinct properties (Tag is useful for this purpose, i.e. 'naming' your objects) for all of your axes, or use enough property/value pairs to narrow the possibilities down to one object. Then use AXES to select the axes, before issuing your plotting command:

axes(h)
