matlab斜线填充直⽅图,matlab能⽤applyhatch画出斜线填充的
直⽅图，但是。。。
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));

main.m⽂件如下：
data=cost_compare(1:20,:);
bar(data,1);
axis([0 21 0.0 40]);
legend('DI demand','DT demand');
%set(gca,'XTickLabel',1:20);
set(gca,'FontSize',14);%只能同时改变x y轴显⽰的字体⼤⼩；
matlab直方图set(gca, 'LineWidth',1);
set(gcf,'color','white')
applyhatch(gcf,'\.x.');
画出的图是下⾯这样的：
失真的很厉害，是对图⽚的再处理，我搜了好久，没有很好地处理⽅案，此处mark⼀下，如果有好的解决⽅案，再回来更新
