Question

假设我有gui代码，通过勾选复选框生成一个图。如何通过删除勾选来删除绘制的图形。提前谢谢。

所以这是我的代码，step1和sound是两个复选框，根据单选按钮生成不同的数字。你可以帮我做一下你用m.file做的事情吗？我真的很感激

function varargout = RotPlot(varargin)
%ROTPLOT M-file for RotPlot.fig
%      ROTPLOT, by itself, creates a new ROTPLOT or raises the existing
%      singleton*.
%
%      H = ROTPLOT returns the handle to a new ROTPLOT or the handle to
%      the existing singleton*.
%
%      ROTPLOT('Property','Value',...) creates a new ROTPLOT using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to RotPlot_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      ROTPLOT('CALLBACK') and ROTPLOT('CALLBACK',hObject,...) call the
%      local function named CALLBACK in ROTPLOT.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

如果要在选中/取消选中此框时切换某些内容的可见性（在您的情况下为绘图对象），则可以执行以下操作。我为每个复选框设置Callback以切换与其关联的绘图的Visible属性。这可以真正适用于切换任何 MATLAB图形对象的可见性。您只需要更改回调中使用的句柄。

fig = figure();
hax = axes('Parent', fig, 'Position', [0.05 0.25 0.9 0.65]);
hplot1 = plot(rand(10, 1));
hold(hax, 'on')
hplot2 = plot(rand(10, 1));

hcheck1 = uicontrol('Style', 'check', ...
                   'parent', fig, ...
                   'value',1, ...
                   'Position', [10 10 200 20], ...
                   'String', 'Show Plot 1');

hcheck2 = uicontrol('Style', 'check', ...
                   'parent', fig, ...
                   'value', 1, ...
                   'Position', [220 10 200 20], ...
                   'String', 'Show Plot 2');

visibility = {'off', 'on'};

set(hcheck1, 'Callback', @(s,e)set(hplot1, 'Visible', visibility{get(s, 'value') + 1}))
set(hcheck2, 'Callback', @(s,e)set(hplot2, 'Visible', visibility{get(s, 'value') + 1}))
