SHM1=SHeatmap(Data,'Format','sq'); SHM1=SHM1.draw(); ```  #### 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(); ```  #### 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(); ```  #### 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'; ```  #### 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(); ```  #### 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(); ```  #### 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 + hex : hexagon ：六边形 + 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 % 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 Format={'sq','pie','circ','oval','hex','asq','acirc'}; A=rand(12,12); B=rand(12,12)-.5; for i=1:length(Format) disp(['Format--',Format{i}]) % 绘制纯正数热图(Draw positive heat map) figure(); SHM_A=SHeatmap(A,'Format',Format{i}); SHM_A=SHM_A.draw(); % exportgraphics(gca,['Format_',Type{i},'_A.png']) % 存储图片 % 绘制含负数热图(Draw heat map with negative number) figure(); SHM_B=SHeatmap(B,'Format',Format{i}); SHM_B=SHM_B.draw(); % exportgraphics(gca,['Format_',Type{i},'_B.png']) % 存储图片 end ```               ### 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(); ```  #### 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) ```  #### 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'); SHM_slan=SHM_slan.draw(); clim([-.7,.7]) colormap(slanCM(i)) SHM_slan.setText(); exportgraphics(gca,['gallery\Colormap_slanCM_',num2str(i),'.png']) end ```        ### 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) ```   ### 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(
