### 1 基础使用(Basic use)
#### 1.1 非负矩阵(Draw positive heat map)

```matlab
figure()
Data=rand(15,15);
SHM1=SHeatmap(Data,'Format','sq');
SHM1=SHM1.draw();
```
![输入图片说明](gallery/Basic_positive.png)

#### 1.2 绘制有负数热图(Contains negative numbers)
```matlab
figure()
Data=rand(15,15)-.5;
SHM2=SHeatmap(Data,'Format','sq');
SHM2=SHM2.draw();
```
![输入图片说明](gallery/Basic_negative.png)

#### 1.3 绘制不同大小热图(Draw heat maps of different sizes)
```matlab
figure()
Data=rand(25,30);
SHM4=SHeatmap(Data,'Format','sq');
SHM4=SHM4.draw();
```
![输入图片说明](gallery/Basic_25_30.png)

#### 1.4 调整colorbar位置(Adjust the colorbar Location)
```matlab
figure()
Data=rand(3,12);
SHM5=SHeatmap(Data,'Format','sq');
SHM5=SHM5.draw();
CB=colorbar;
CB.Location='southoutside';
```
![输入图片说明](gallery/Basic_colorbar_location.png)

#### 1.5 绘制有NaN热图(Draw heat map with NaN)
```matlab
figure()
Data=rand(12,12)-.5;
Data([4,5,13])=nan;
SHM6=SHeatmap(Data,'Format','sq');
SHM6=SHM6.draw();
```
![输入图片说明](gallery/Basic_with_NaN.png)

#### 1.6 绘制有文本热图(Draw heat map with texts)

使用 setText() 方法显示文字：
Use the setText() method to display text:
```matlab
figure()
Data=rand(12,12)-.5;
Data([4,5,13])=nan;
SHM7=SHeatmap(Data,'Format','sq');
SHM7=SHM7.draw();
SHM7.setText();
```
![输入图片说明](gallery/Basic_with_text.png)

#### 1.7 绘制带标签热图(Draw heat map with labels)

改x轴y轴标签就还是设置 XTickLabel 和 YTickLabel :
Change the x-axis and y-axis labels by setting XTickLabel and YTickLabel :
```matlab
figure()
Data=rand(12,12);
SHM8=SHeatmap(Data,'Format','sq');
SHM8=SHM8.draw(); 
ax=gca;
ax.XTickLabel={'X-1','X-2','X-3','X-4','X-5','X-6','X-7','X-8','X-9','X-10','X-11','X-12'};
ax.YTickLabel={'Y-1','Y-2','Y-3','Y-4','Y-5','Y-6','Y-7','Y-8','Y-9','Y-10','Y-11','Y-12'};
ax.FontSize=14;
```

### 各类型热图绘制(Preparation of various Format of heat maps)
+ sq    : square (default)     : 方形(默认)
+ pie   : pie chart                : 饼图   
+ circ  : circular                   : 圆形
+ oval  : oval                       : 椭圆形

+ asq   : auto-size square   ：自带调整大小的方形
+ acirc : auto-size circular   ：自带调整大小的圆形

```matlab
% sq    : square (default)   : 方形(默认)
% pie   : pie chart          : 饼图   
% circ  : circular           : 圆形
% oval  : oval               : 椭圆形
% hex   : hexagon            ：六边形

### 3 调整colormap(Adjust colormap)
#### 3.1 调整clim(Adjust clim)

使用 clim() 或者 caxis() 调整颜色映射范围
Use function clim() or caxis() to set the CLim
```matlab
fig=figure('Position',[50,50,1400,700]);
% random data
Data=rand(12,12)-.5;
Data([4,5,13])=nan;
% subplot1
ax1=axes('Parent',fig,'Position',[0+1/40,0,1/2-1/20,1]);
SHM_ax1=SHeatmap(Data,'Format','sq','Parent',ax1);
SHM_ax1=SHM_ax1.draw();
SHM_ax1.setText();
% subplot2 adjust clim
ax2=axes('Parent',fig,'Position',[1/2+1/40,0,1/2-1/20,1]);
SHM_ax2=SHeatmap(Data,'Format','sq','Parent',ax2);
SHM_ax2=SHM_ax2.draw();
clim([-.8,.8])
SHM_ax2.setText();
```
![输入图片说明](gallery/Colormap_clim.png)

#### 3.2 使用MATLAB自带colormap(Use the built-in colormap in MATLAB)
```matlab
figure()
Data=rand(14,14);
SHM_Bone=SHeatmap(Data,'Format','sq');
SHM_Bone.draw();
colormap(bone)
```
![输入图片说明](gallery/Colormap_bone.png)

#### 3.3 slanCM(slanCM colormap)
Zhaoxu Liu / slandarer (2023). 200 colormap (https://www.mathworks.com/matlabcentral/fileexchange/120088-200-colormap), MATLAB Central File Exchange. 检索来源 2023/3/15.
```matlab
% 单向colormap或离散colormap
for i=[20,21,61,177]
    figure()
    Data=rand(14,14);
    SHM_slan=SHeatmap(Data,'Format','sq');
    SHM_slan.draw();
    colormap(slanCM(i))
    exportgraphics(gca,['gallery\Colormap_slanCM_',num2str(i),'.png'])
end
% 双向colormap(Diverging colormap)
for i=[141,136,134]
    figure()
    Data=rand(14,14)-.5;
    SHM_slan=SHeatmap(Data,'Format','sq');

### 4 整体修饰(Overall decoration)

setBox   ：修饰边框
setPatch ：修饰图形
setText  ：修饰文本
```matlab
figure()
Data=rand(10,10);

SHM=SHeatmap(Data,'Format','pie');
SHM=SHM.draw(); 
% 容器边框设置为蓝色
% 图形边框设置为红色
% The container box border is set to blue
% The drawing border is set to red
SHM.setBox('Color',[0,0,.8])
SHM.setPatch('EdgeColor',[.8,0,0])


figure()
Data=rand(10,10);
Data([4,5,13])=nan;

SHM=SHeatmap(Data,'Format','sq');
SHM=SHM.draw(); 
% 设置文本为蓝色并修改字号
% Set the text to blue and modify the font size
SHM.setText('Color',[0,0,.8],'FontSize',14)
```
![输入图片说明](gallery/All1.png)
![输入图片说明](gallery/All2.png)

### 5 局部修饰(Partial decoration)

setTextMN
setPatchMN
设置第m行n列对象的属性：举个例子，把数值大于0.9部分文字变为星号，并用红色框框起来，并改编NaN处颜色。

Set the attributes of the object in row m and column n: for example, change the text with a value greater than 0.9 into an asterisk, frame it in red, and adapt the color at NaN.
```matlab
figure()
Data=rand(9,9);
Data([4,5,13])=nan;
% 绘制方块形状热图
SHM=SHeatmap(Data,'Format','sq');
SHM=SHM.draw();
% 显示文本(Show Text)
SHM.setText(); 
for i=1:size(Data,1)
    for j=1:size(Data,2)
        if Data(i,j)>=.9
            SHM.setTextMN(i,j,'String','**','FontSize',20)         % 修改>=0.9方块颜色
            SHM.setPatchMN(i,j,'EdgeColor',[1,0,0],'LineWidth',2)  % 修改>=0.9方块文本为**
        end
        if isnan(Data(i,j))
            SHM.setPatchMN(i,j,'FaceColor',[.8,.6,.6]) % 修改NaN处颜色
        end
    end
