用Matlab绘制柱状图

类型一：

% 生成儿童疾病案例相关数据

measles = [75.6];
mumps = [80.12];
chickenPox = [4.7];

% 利用bar函数创建垂直条形图
figure
bar([measles' mumps'], 0.5)

% 设置坐标轴范围
axis([0 3 0 100])
set(gca, 'XTick', 1:2)
set(gca,'XTickLabel',{'KNN','GCN'});

ylabel('准确度')

类型2：

% data = [23.7,12.63,1.38,7.72;8.2,1.29,0.5,1.72;14.8 28.72,34.6,22.65;9.7,9.56,12.14,15.75;43.6,49.8,51.38,52.16];
data = [23.7,20.8,1.38,7.72;8.2,3,0.5,1.72;14.8 16.4,34.6,22.65;9.7,11.7,12.14,15.75;43.
