matlab画柱状图并填充斜线_matlab画柱状图分两类

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。

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

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));

%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.
