matlab 画图

字体- FontName

字体大小 - FontSize

设置坐标轴字体 直接在图后 set（gca,'FontSize',20）

设置legend    L

L = legend(['FeatureBagging, Auc = ',num2str(Ave.auc(time,2))],['ActiveOutlier, Auc = ',num2str( Ave.auc(time,3))],['LOF, Auc = ',num2str(  Ave.auc(time,4))],['ParzenWindow, Auc = ',num2str(  Ave.auc(time,5))],['L21, Auc = ',num2str(  Ave.auc(time,6))],['L20-4, Auc = ',num2str( 

set(L,'Fontname','times new Roman','fontsize',15)

常用字体 - 'times new Roman'

Title

title(['\fontsize{12}\fontname{宋体}汉字 \fontname{Times new roman}this is English,这是汉字,Hello World 123'])

sbuplot 加一个大标题

suptitle('title')

---

Bar

figure()

b = bar([Accuracy_SVM;Accuracy_DBSCAN;Accuracy_LOF])

hx = [0.8 1 1.2 1.8 2 2.2 2.8 3 3.2]-0.08 % 纵坐标

hy = reshape(cell2mat(get(b,'YData')),1,9)+0.01;

str ={};

限制坐标轴的范围

坐标轴的显示范围？可用axis函数

% 二维

axis([xmin xmax ymin ymax]) %xmin是x最小，xmax是x最大，ymin，ymax类似

% 三维

axis([xmin xmax ymin ymax zmin zmax])

---

for i=1:length(hy)

str{i} = num2str(hy(i));

end

% 添加标签

text(hx, hy(:)+0.01,str);

title(strcat('Accuracy'))

legend('RP','PCA','Autoencoder')

set(gca,'XTickLabel',{'SVM','DBSCAN','LOF'})

saveas(gcf,strcat(path,'\Synthesis_Accuracy_RobotFailure.fig'))

saveas(gcf,strcat(path,'\Synthesis_Accuracy_RobotFailure.pdf'))

save(strcat(path,'\Info_Synthesis_Accuracy_RobotFailure.mat','Accuracy_SVM','Accuracy_DBSCAN','Accuracy_LOF','AUC_SVM','AUC_LOF'))

set(gca, 'LineWidth',1) % 设置当前图片外围线宽

对于Bar上方的数据位置除了get外有他方法么？ 目前我是自己调的
