在 MATLAB R2011b 中，我有一个脚本，它明确指定了一个数字（比如图 1）并在其上绘图。我希望保持此图打开并使用不同的参数再次运行脚本，以便我可以直观地比较新图和以前的图。

如何重命名前一个图（例如，图 2），以便新图不会覆盖它，从而允许两个图都可见，而无需

  • 修改脚本，或
  • 将前一个图形保存为 .fig 文件并将其重新打开为另一个图形

从两者

  1. 命令行，和
  2. 使用图形的 GUI？

您可以使用getobj将一个图形的内容复制到另一个图形：

% get handle of the old figure
oldFigHandle = gcf;

% create new figure 
newFigHandle = figure+1;

% copy the contents from one figure the other
copyobj(get(oldFigHandle , 'children'), newFigHandle);

可以使用set和get命令复制其他属性：

set(newFigHandle, 'color', get(oldFigHandle , 'color'));

根据 H.Muster 的回答，我编写了这个函数来克隆一个图形：

%% Clone a figure
%  clone_figure()     - Clone the current figure to a new figure
%  clone_figure(N)    - Clone the current figure to figure N
%  clone_figure(0, M) - Clone figure M to a new figure
%  clone_figure(N, M) - Clone figure M to a figure N
function clone_figure(new_index, old_index)
    % Get handle of original figure
    if (exist('old_index', 'var'))
        if (not(ishandle(old_index)))
            error('myApp:argChk', ['Figure ',num2str(old_index),' undefined']);
        end
        figure(old_index);
    end
    old_handle = gcf;
    % Get handle of clone
    if (exist('new_index', 'var') && new_index)
        if (new_index < 0)
            error('myApp:argChk', ['Index ',num2str(new_index),' invalid']);
        end
        figure(new_index);
    else
        figure;
    end
    new_handle = gcf;
    % Copy figure's contents and properties

刚刚与 Mathworks 员工交谈，并被告知更好的解决方案是将图形的“HandleVisibility”参数设置为“关闭”以保护它。例如，要保留图 1 和图 2，请执行

 set(1:2, 'HandleVisibility', 'off')

然后，MATLAB 会将对这些图形的任何引用映射到新图形，以便原始图形（包括工具设置）保持不变。

虽然这并不能完全回答问题，但它实现了我想要做的。

您可以只保存当前图形的句柄

h = [];
for i = 1:NumGraphs
    h(i) = gcf;
    figure;

    %Your code to create the next graph here
end

然后返回一个特定的图表：

figure(h(i));
