MATLAB实例:绘制条形图
作者:凯鲁嘎吉 - 博客园 http://www.cnblogs.com/kailugaji/
用MATLAB绘制条形图,自定义条形图的颜色、图例位置、横坐标名称、显示条形图上面的数字,并保存图片到指定位置。
1. demo.m
clear clc Y=[0.6 0.7 0.75 0.9 0.91 0.92 0.9 0.92 0.95 0.84 0.86 0.87]; figure X=1:4; h=bar(X,Y); % 设置条形图颜色 set(h(1),'FaceColor',[1,1,0]) set(h(2),'FaceColor',[0,0.9,0.3]) set(h(3),'FaceColor',[1,0,0.3]) ylim([0,1]); ylabel('Accuracy'); xlabel('Datasets'); legend('Method 1','Method 2','Method 3', 'FontSize',8,'FontName','Times New Roman', 'Location', 'northwest'); %修改图例 set(gca,'xtick',1:4); set(gca,'XTickLabel',{'dataset 1','dataset 2','dataset 3','dataset 4'},'FontSize',12,'FontName','Times New Roman'); %修改横坐标名称、字体 Y_1=roundn(Y,-2); for i = 1:length(X) text(X(i)-0.25,Y_1(i,1),num2str(Y_1(i,1)),'HorizontalAlignment','center','VerticalAlignment','bottom','FontSize',8,'FontName','Times New Roman'); text(X(i),Y_1(i,2),num2str(Y_1(i,2)),'HorizontalAlignment','center','VerticalAlignment','bottom','FontSize',8,'FontName','Times New Roman'); text(X(i)+0.25,Y_1(i,3),num2str(Y_1(i,3)),'HorizontalAlignment','center','VerticalAlignment','bottom','FontSize',8,'FontName','Times New Roman'); end saveas(gcf,sprintf('条形图.jpg'),'bmp'); %保存图片
