在Matlab指南中旋轉整個軸

Question

我正在嘗試旋轉一個名爲axes1的整個軸。

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

上面的代碼啓動30度的旋轉。但是，圖像是旋轉的，但不是整個軸1。我已經測試了諸如rotate3D之類的指南工具，但是rotate3D無法成功地用於2D圖像。我也試過set(handles.axes1,'Rotation',-25);，這沒有效果。它只是忽略了陳述，並繼續進行其他任務。有沒有辦法旋轉整個軸？

Answer 1

可以使用view載體作用旋轉軸。

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 

這也適用於標準樣：

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 

編輯以下

我已經創建了一個評論簡單的GUI具有兩個axes和兩個pushbutton具有以下tag

• 軸＃1：axes1
• 軸＃2：axes2
• 按鈕＃1：pushbutton1
• 按鈕＃2：pushbutton2

callback的按鈕1在軸上加載圖像1，轉動軸。

的的callbackpushbutton2地塊在axes2的曲線，所述轉動軸。

的GUI工作正常，axers旋轉預期。

這是GUI的.m;您可以測試它是如何創建GUI並使用上面指定的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)".
