导读：记录一下如何使用matlab画柱状图，并进行填充。
版本：
    matlab 2017b.
注意：使用matlab2016版本似乎会有bug。

1.辅助函数makehatch.m

function A = makehatch(hatch)
%MAKEHATCH Predefined hatch patterns
%  MAKEHATCH(HATCH) returns a matrix with the hatch pattern for HATCH
%   according to the following table:
%      HATCH        pattern
%     -------      ---------
%        /          right-slanted lines
%        \          left-slanted lines
%        |          vertical lines
%        -          horizontal lines
%        +          crossing vertical and horizontal lines
%        x          criss-crossing lines
%        .          single dots

n = 6;
A=zeros(n);
switch (hatch)
 case '/'
  A = fliplr(eye(n));
 case '\'
  A = eye(n);
 case '|'
  A(:,1) = 1;
 case '-'
  A(1,:) = 1;
 case '+'
  A(:,1) = 1;
  A(1,:) = 1;
 case 'x'
  A = eye(n) | fliplr(diag(ones(n-1,1),-1));
 case '.'
  A(1:2,1:2)=1;
 otherwise
  error(['Undefined hatch pattern "' hatch '".']);
end

2.辅助函数applyhatch.m

function applyhatch(h,patterns,colorlist)
%APPLYHATCH Apply hatched patterns to a figure
%  APPLYHATCH(H,PATTERNS) creates a new figure from the figure H by
%  replacing distinct colors in H with the black and white
%  patterns in PATTERNS. The format for PATTERNS can be
%    a string of the characters '/', '\', '|', '-', '+', 'x', '.'
%    a cell array of matrices of zeros (white) and ones (black)
%
%  APPLYHATCH(H,PATTERNS,COLORS) maps the colors in the n by 3
%  matrix COLORS to PATTERNS. Each row of COLORS specifies an RGB
%  color value.
%
%  Note this function makes a bitmap image of H and so is limited
%  to low-resolution, bitmap output.
%
%  Example 1:
%    bar(rand(3,4));
%    applyhatch(gcf,'\-x.');
%
%  Example 2:
%    colormap(cool(6));
%    pie(rand(6,1));
%    legend('Jan','Feb','Mar','Apr','May','Jun');
%    applyhatch(gcf,'|-+.\/',cool(6));

  bits = print(h,'-RGBImage','-r0');
end
set(h,'paperpositionmode',oldppmode);

bwidth = size(bits,2);
bheight = size(bits,1);
bsize = bwidth * bheight;
if ~isempty(colorlist)
  colorlist = uint8(255*colorlist);
  [colors,colori] = nextnonbw(0,colorlist,bits);

3.画柱状图的.m文件,其中调用了applyhatch()函数

%If you want to adjust the pattern to 6 bar such as " applyhatch(gcf,'.-+/|x');",
%try to type this "applyhatch(gcf,'.-++/||xx');" instedly. 
%So you can avoid the duplicated pattern at least, even order problem is still not solved. 
data=[345,359,209;155,161,99];%三列的柱状图，分为了两种，具体见图

b=bar(data);%画柱状图

text(0.73,345+12,'345');%设置柱状图上的数值大小
text(0.73+0.23,359+12,'359');
text(0.73+0.45,209+12,'209');

text(0.73+1,155+12,'155');
text(0.73+1+0.23,161+12,'161');
text(0.73+1+0.46,99+12,'99');

grid on;%添加网格线
%ch = get(b,'children');
title('实验2')
set(gca,'XTickLabel',{ 
   'LINEITEM','ORDERS'})%设置X轴显示

%set(ch,'FaceVertexCData',[0 0 1;1 0 0;0 1 0])
legend('分区1','分区2','分区2');%设置
ylabel('时间(秒）');%设置y轴名字
applyhatch(gcf,'/\xx');%对原图添加填充，这里有个bug就是xx需要输入两次
