代码如下：

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));

% 而applyhatch函数需要调用下面的函数

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

测试代码如下：

data = [96.3,92.6,71.2;95.7,93.6,83.9;96.8,94.3,78.3;95.8,92.7,80.3]
 bar(data,1)
 axis([0 6 0.0 100])
 legend('方法','exited','Square')
 set(gca,'XTickLabel',{'Img1','Img2','Img3','Img4'})
 applyhatch(gcf,'\.x.')

结果如下：

也就是，引入上面的函数，画，柱形图的时候加上这一句就可以了

 applyhatch(gcf,'\.x.')

实际上饼型图也可以，上面有个实例，我测试结果如下

http://img.ph.126.net/jVvdh8fZeyeoWuKqPnKUbw==/2854437738824391860.jpg

 语句复杂一点点

applyhatch(gcf,'|-+.\/',cool(6));

这段代码也有点生成的图片估计是固定大小的，这样，论文中用这些图片还是有麻烦的，不知道该怎么设置？
