在 Matlab 指南中旋转整个轴

Rotating an entire axes in Matlab Guide

我目前正在尝试旋转名为 axes1 的整个轴。

                imr=imrotate(img,30);
                axes(this.gui_h.axes1);
                imshow(imr,'Parent',this.gui_h.axes1);

上面的代码启动了 30 度的旋转。但是,图像旋转但不是整个轴 1。我已经测试了诸如 rotate3D 之类的引导工具,但是 rotate3D 不能成功地用于 2d 图像。我也试过 set(handles.axes1,'Rotation',-25); ,但没有效果。它只是忽略该语句并继续执行其他任务。有没有办法旋转整个轴?

您可以使用 view 函数来旋转轴。

imshow('Jupiter_New_Horizons.jpg')
xlabel('X axis')
ylabel('Y axis')
camzoom(.8)

% Rotate the axes changing the Azimuth value
for i=0:-3:-180
   view([i 90]);
   pause(.3)
end

这也适用于标准地块:

t=0:.1:2*pi;
x=sin(t)
plot(t,x);
grid minor
xlabel('X axis')
ylabel('Y axis')
camzoom(.8)
for i=0:-3:-180
   view([i 90]);
   pause(.3)
end

根据评论进行编辑

我创建了一个简单的 GUI,其中包含两个 axes 和两个 pushbutton,以及以下 tag

  • 轴 #1:轴 1
  • 轴 #2:轴 2
  • 按钮 #1:按钮 1
  • 按钮 #2:按钮 2

pushbutton1callbackaxes1中加载图像,旋转轴。

pushbutton2callbackaxes2上绘制一条曲线,旋转轴。

GUI 工作正常,轴按预期旋转。

这是GUI的.m;您可以测试它创建 GUI 并使用上面指定的 tag

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