利用Matlab实现阴影柱状图的绘制

作者:slandarer

阴影柱状图绘制的代码MATHWORKS上也有,不过是生成图片后,识别图像上不同颜色块并直接修改像素生成阴影线。这样的生成方式不可逆且自由度较低,所以本文为大家带来的是一个直接画线条填充的硬画版本,希望有所帮助

阴影柱状图绘制的代码MATHWORKS上也有,不过是生成图片后,识别图像上不同颜色块并直接修改像素生成阴影线,这样的生成方式不可逆且自由度较低,因此本人开发了一个直接画线条填充的硬画版本。

另:由于不太想动脑子,使用polyshape对象进行了交点判定,减少了代码出错的概率,但由于代码开发基于polyshape对象,阴影柱状图绘制函数理论上需要至少R2017b及之后版本才能使用(越新越好)。(再安利一下polyshape对象,属实太好用了)

由于工具函数过长,将被放在最后展示,以下将先展示函数用法。

示例图

使用教程

1.基本使用

就短短三行代码就能画,真的简单:

y=[2 2 -3 -2 -5; -2 -5 6 2 5; 9 8 9 2 5];

SH=shadowHist(y,'ShadowType',{'/','\','.','x','|'});
SH=SH.draw();

2.添加图例

使用legend函数添加图例,使用方式如下:

y=[2 2 3 2 5; 2 5 6 2 5; 9 8 9 2 5];

SH=shadowHist(y,'ShadowType',{'/','\','.','_','+'});
SH=SH.draw();
SH=SH.legend({'AAAAAAA','BBBBBBB','CCCCCCC','DDDDDDD','EEEEEEE'},'FontName','Arial','FontSize',11);

图例是自行绘制的,能拖动及自动缩放(老难算了这玩意):

3.阴影格式

阴影有:\,/,_,|,+,x,.,w,k,g十种格式,以下全部展示一下:

y=[2 2 3 2 5 4 2 2 2 1;2 2 3 2 5 4 2 4 3 6];

SH=shadowHist(y,'ShadowType',{'/','\','x','.','_','|','+','w','k','g'});
SH=SH.draw();
SH=SH.legend({'A','B','C','D','E','F','G','H','I','J'});

4.特殊结构

含负数

y=[2 2 -3 -2 -5; -2 -5 6 2 5; 9 8 9 2 5];

SH=shadowHist(y,'ShadowType',{'/','\','.','x','|'});
SH=SH.draw();

堆叠柱状图

y=[2 2 -3 -2 -5; -2 -5 6 2 5; 9 8 9 2 5; -3 -5 6 2 5; 4 8 5 2 5];

SH=shadowHist(y,'ShadowType',{'/','\','.','x','|'},'stacked');
SH=SH.draw();

5.额外修饰

阴影、柱状图框、图例框分别具有barShadow,barBox,lgdBox的标签,使用findobj获取对象并循环修饰即可,不过为了绘制更好看,部分阴影使用plot绘制部分则是使用scatter绘制,因此阴影修饰时要用if先检测一下格式,给个示例:

y=[2 2 3 2 5; 2 5 6 2 5; 9 8 9 2 5];

SH=shadowHist(y,'ShadowType',{'/','\','.','_','+'});
SH=SH.draw();
SH=SH.legend({'AAAAAAA','BBBBBBB','CCCCCCC','DDDDDDD','EEEEEEE'},'FontName','Cambria','FontSize',11);

% 修饰阴影变成红色并加粗
shadowHdl=findobj('Tag','barShadow');
for i=1:length(shadowHdl)
    if isa(shadowHdl(i),'matlab.graphics.chart.primitive.Line')
        shadowHdl(i).Color=[.8,.6,.6];
        shadowHdl(i).LineWidth=1;
    else
        shadowHdl(i).MarkerFaceColor=[.8,.6,.6];
        shadowHdl(i).SizeData=5;
    end
end

% 修饰框变为蓝色并加粗
boxHdl=findobj('Tag','barBox');
for i=1:length(boxHdl)
    boxHdl(i).EdgeColor=[.3,.3,.8];
    boxHdl(i).LineWidth=2;
end

% 图例框加粗并变成绿色
lgdBox=findobj('Tag','lgdBox');
lgdBox.LineWidth=1.3;
lgdBox.EdgeColor=[.1,.3,.1];
lgdBox.FaceColor=[173,189,163]./255;

光看上面代码大佬们应该就已经懂了咋用,如果比较小白,可以直接使用MATLAB自带的属性修饰器:
