我有点迷路了......我有一个 .m 文件，它通过保持和“立即绘制”重复地将冲浪图绘制成一个图形，以创建动画。

我现在创建了一个 GUI（标签：'GUI'），其中包含为模拟设置参数的指南。在 GUI 中设置参数并按下按钮后，我希望模拟像以前一样开始，但不是打印到图形我希望它现在打印到 GUI 中的轴对象（标签：'GUI_panel_plot_axes_fullframe'）。

如何从 .m 文件中访问 GUI 中的轴对象？我尝试了以下方法但没有成功：

h = findobj('Tag','GUI');
handles = guihandles(h);
axes(handles.GUI_panel_plot_axes_fullframe);

但是，尝试访问应包含我的轴对象句柄的句柄对象时出现错误：

Error using guihandles
H must be the handle to a figure or figure descendent.

我愿意改变我访问句柄的方式......我已经尝试了多个在互联网上漫游的版本，但没有任何一个运气！任何帮助深表感谢！

如果不查看其余代码，很难告诉您错误。无论如何，这是一个使用“指南”创建的非常简单的 GUI 示例。正如您所看到的，当您按下按钮时，图像被绘制到称为“axes1”的轴上。我想你可以明白的。

function varargout = untitled(varargin)
    % UNTITLED MATLAB code for untitled.fig
    %      UNTITLED, by itself, creates a new UNTITLED or raises the existing
    %      singleton*.
    %
    %      H = UNTITLED returns the handle to a new UNTITLED or the handle to
    %      the existing singleton*.
    %
    %      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
    %      function named CALLBACK in UNTITLED.M with the given input arguments.
    %
    %      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
    %      existing singleton*.  Starting from the left, property value pairs are
    %      applied to the GUI before untitled_OpeningFcn gets called.  An
    %      unrecognized property name or invalid value makes property application
    %      stop.  All inputs are passed to untitled_OpeningFcn via varargin.
    %
    %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
    %      instance to run (singleton)".
