MATLAB 句柄绘图

一、线句柄实例

>> h1=line([0:10],[0:10])%创建句柄值

h1 =

设置线条和窗口颜色

>> set(h1,'color',[1 0 0])%线条红色
>> set(gcf,'color','b')%背景蓝色

二、

clear 
x=0:2*pi/180:2*pi;
y1=sin(x);
y2=cos(x);
plot(x,y1,x,y2,x,zeros(size(x)),'w');

h=get(gcf,'children');%得到图片属性
hh=get(gca,'children');%得到三条线的的属性
y11=get(hh(2),'ydata');%获取cos(x)的幅度,等于y2
set(hh(2),'ydata',y11/2);%设置新的幅度
set(hh(3),'linestyle','-.');%设置格式

set(gca,'DefaultTextColor',[1 0 0])%设置字体颜色
gtext('正弦')%添加字体,鼠标选择位置,点击出现
gtext('余弦')

set(0,'defaultfigurecolor',[0.9 0.9 0.9])%设置图片背景颜色
set(0,'defaultfigurecolor','default')%恢复为默认值

k=menu('请选择','plot','mesh','surf')

 二、

1、把控件安装在图形窗口上

clear 
h1=uicontrol('style','edit','tooltipstring','edit text')
h2=uicontrol('style','checkbox','position',[90 20 30 20],'tooltipstring','checkbox')
h3=uicontrol('style','listbox','position',[150 20 40 20],'tooltipstring','listbox')%[a b c d],(a,b)左下角位置,(c,d)宽和高
h4=uicontrol('style', 'pushbutton', 'Position' ,[210,20,30,20],'TooltipString', 'pushbutton')
h5=uicontrol('style', 'radiobutton', 'Position' ,[260,20,30,20],'TooltipString', 'Radiobutton')

2、

clear all
axes('position',[0.1 0.1 0.5 0.2])%坐标位置
x=0:0.5:10;y=x;plot(x,y)
axis([0 10 2 10])%显示范围

3、

clear all
subplot(2,1,1)
membrane %这是一个库函数
light('color',[0.9 0.5 0.1],'position',[0,-2,1])%风格省略为无穷远,光顺序通过(0 0 0)和(0 -2 1)
subplot(2,1,2)
membrane
light('color',[0.9 0.0 0.1],'style','local','position',[1,-1,1])%风格为本地光,光源在(1 -1 1)位置

4、

clear all
figure('color',[1 0.1 0],'position',[0 0 200 100],'name','ww')

 三、imagesc

1、imagesc(A)将矩阵A中的元素数值按大小转化为不同颜色,并在坐标轴对应位置处以这种颜色染色。

clear all
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(C)
colorbar

2、更改坐标轴

clear all
x = [5 8];
y = [3 6];
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(x,y,C)
colorbar

翻转y轴

clear all
x = [5 8];
y = [3 6];
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(x,y,C)
colorbar
axis xy;

clear all
x = [5 8];
y = [3 6];
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(x,y,C)
colorbar
axis xy%翻转y轴
set(gca,'XDir','reverse')%翻转x轴

  

3、限制高度

C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
clims = [4 18];
imagesc(C,clims)
colorbar

4、更改显示色调

clear
C = [1 2 3; 4 5 6; 7 8 9];
im = imagesc(C);
im.AlphaData = .5;

5、投影面

clear
Z = 10 + peaks;
surf(Z)
hold on
imagesc(Z)
colorbar

 四、shading阴影函数

clear all
figure
subplot(2,2,1)
sphere(16)
title('Faceted Shading (Default)')

subplot(2,2,2)
sphere(16)
shading flat
title('Flat Shading')

subplot(2,2,3)
sphere(16)
shading interp
title('Interpolated Shading')

五、colorbar函数颜色

1、

close all; clear all; clc
figure(1)
surf(peaks(30))
colorbar('YTickLabel',{'Freezing','Cold','Cool','Neutral','Warm','Hot','Burning','Nuclear'})

2、

close all; clear all; clc
figure(1)
surf(peaks(30))
colormap jet
colorbar('YTickLabel',{'Freezing','Cold','Cool','Neutral','Warm','Hot','Burning','Nuclear'})

3、

close all; clear all; clc
figure(1)
surf(peaks(30))
colormap jet

colorbar('location','SouthOutside','YTickLabel',{'Freezing','Cold','Cool','Neutral','Warm','Hot','Burning','Nuclear'})

六、findobj

1、

close all;clear;clc;
plot(1:10)
xlabel xlab %x轴名称为“xlab”
disp('findobj返回的对象句柄')
h=findobj
h1=findobj('tag','figure')
