matlabbar填充花纹,Matlab中画花纹填充的柱状图在画柱状图时，利⽤不同的颜⾊区分在实际打印时经常区分不出。
为了能够更清楚第表⽰最终结果，可采⽤在柱状图中打阴影的⽅式来表⽰。
然⽽，Matalab本⾝没有提供实现这种功能的函数库。
下⾯两个函数：
% ApplyBrandon
's function
applyhatch_pluscolor母亲节快乐的英文
% Apply Brian'sfunction
applyhatch_plusC(fH,'\-x.', 'rkbk');
实现了上述功能。
这两个函数中都调⽤了函数makehatch_plus源码如下(都已经调试通过，可⽅便使⽤)。
h = bar(rand(3,4));
%随机⽣成3⾏4列的矩阵
fH = gcf;
colormap(jet(4));
%参数4表⽰4列数的颜⾊
legend('Apple', 'Orange', 'Banana','Melon', 'Location',
'EastOutside');
% Apply
Brandon'sfunction(PS：接着上⾯的代码写)
tH = title('Brandon''s applyhatch');
applyhatch_pluscolor(fH,'\-x.', 0, [1 0 1 0], jet(4));
%参数4可改变
% Apply Brian'sfunction
t(tH, 'String','Brian''s applyhatch');
applyhatch_plusC(fH,'\-x.', 'rkbk');
t(tH, 'String','Original');

% APPLYHATCH_PLUSCOLOR(H,PATTERNS) creates anew figure from the figure H by
% replacing distinct colors in H with
the blackand white
% patterns in PATTERNS. The format for PATTERNScan be
% a
string of the characters:
%
'/', '\', '|', '-', '+', 'x', '.', 'c','w', 'k'
%
(e makehatch_plus.m for more details) or
% a
cell array of matrices of zeros (white) andones (black) %
% In addition, H can alternatively be a
uint8NxMx3 matrix of the type
% produced by imread.
In this ca, colors in this image will be
% replaced with patterns as if it was
afigure. A final figure window
% will be generated that displays
theresult. The DPI argument
% discusd below will be ignored if H
is animage matrix.
%
% APPLYHATCH_PLUSCOLOR(H,PATTERNS,CVBW) binaryvalue for choice of Color or Black
% and White plots. If color is chon
the colorwill match that of the
% current fill. 1 ->

%
APPLYHATCH_PLUSCOLOR(H,PATTERNS,CVBW,HINVERT)binary value to invert the hatch.
% i.e., if it is black lines with a
whitebackground, that becomes white
% lines with a black background. This
can eitherbe a scalar value or a
% 1xN array equal to the length of
PATTERNS.When ud as an array each
% PATTERNS(i) will be inverted according
toHinvert(i). 1 -> Invert,
% anything el -> Non
Inverted
%
% APPLYHATCH_PLUSCOLOR(H,PATTERNS,CVBW,HINVERT,COLORS)
maps the colors inthe n by 3
% matrix COLORS to PATTERNS. Each row of
COLORSspecifies an RGB
% color value.
