先看效果图

带填充纹理的堆叠图是通过在原始堆叠图的基础上添加不同的纹理得到的，可以很好地解决由于颜色区分不够而导致的对象识别困难问题。由于Matlab中未收录提供填充纹理选项，因此给出一个自行开发的代码来实现该功能，

1、柱状图填充

clc
close all
clear
%% Example 1：柱状图填充
figure(1);
h = bar(rand(3,4));
xlabel('Xlabel','fontsize',14,'FontName','Times New Roman','FontWeight','Bold')
ylabel('Ylabel','fontsize',14,'FontName','Times New Roman','FontWeight','Bold')
set(gca,'Layer','top','FontSize',14,'Fontname', 'Times New Roman');
figure(2);
hp = bar(rand(3,4));
xlabel('Xlabel','fontsize',14,'FontName','Times New Roman','FontWeight','Bold')
ylabel('Ylabel','fontsize',14,'FontName','Times New Roman','FontWeight','Bold')
set(gca,'Layer','top','FontSize',14,'Fontname', 'Times New Roman');
hatchfill2(hp(1),'single','HatchAngle',0);
hatchfill2(hp(2),'cross','HatchAngle',45);
hatchfill2(hp(3),'single','HatchAngle',90);

2、饼图填充

clc
close all
clear
%% Example 2：饼图填充
figure(3);
colormap(cool(4));
h = pie(rand(4,1));
th = findobj(gca, 'Type', 'text');
set(th, 'FontName', 'Times New Roman', 'FontSize', 12)
hl = legend('Jan','Feb','Mar','Apr','May','Jun');
set(hl,'Box','off','Location','southOutside','NumColumns',3);
set(gca,'Layer','top','FontSize',14,'Fontname', 'Times New Roman');
figure(4);
colormap(cool(4));
hp = pie(rand(4,1));
hatchfill2(hp(1,1),'single','HatchAngle',0);
hatchfill2(hp(1,3),'cross','HatchAngle',45);
hatchfill2(hp(1,5),'single','HatchAngle',60);
hatchfill2(hp(1,7),'single','HatchAngle',90);
th = findobj(gca, 'Type', 'text');
set(th, 'FontName', 'Times New Roman', 'FontSize', 12)
hl = legend(hp(1, [1,3,5,7]),'Jan','Feb','Mar','Apr');
set(hl,'Box','off','Location','southOutside','NumColumns',3);
set(gca,'Layer','top','FontSize',14,'Fontname', 'Times New Roman');
