baidu的。

主程序。

暂定好用。

颜色的可以自己定义，matlab就有。

斜线和X在applyhatch里有。

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]

applyhatch(gcf,'\.x.')

applyhatch函数：

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

补充内容 (2013-11-7 10:52):

修改后的函数.m文件在21楼。有坛友说网上下的无法很好的运行。这个应该可以。请大家下载尝试。

有问题，请邮件我。谢谢。
