本期推送教大家如何绘制各种样式的山脊图，这里做了一个工具函数用来实现好看的山脊图的绘制，编写不易请多多点赞，大体绘制效果如下：
依旧工具函数放在文末。

0 数据准备
数据为多个一维向量放在元胞数组中，大概像这样：
X1=normrnd(2,2,1,50);
X2=[normrnd(4,4,1,50),normrnd(5,2,1,50)];
X3=[normrnd(6,2,1,50),normrnd(8,4,1,50)];
X4=[normrnd(12,1,1,50),normrnd(12,4,1,50)];
X5=[normrnd(10,2,1,50),normrnd(10,4,1,50)];
X6=[normrnd(7,2,1,50),normrnd(7,4,1,50)];
X7=[normrnd(4,2,1,50),normrnd(4,4,1,50)];
Data={X1,X2,X3,X4,X5,X6,X7};
1 基础绘制:上色类型
通过设置ColorMode属性设置上色方式，可设置为：
- Order
- X
- GlobalX
- Kdensity
- Qt
Order：每个山脊不同颜色
JP=joyPlot(Data,'ColorMode','Order');
JP=JP.draw();
绘制并添加图例(同时可以通过MedLine设置显示中位线)：
JP=joyPlot(Data,'ColorMode','Order','MedLine','on');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
可以通过设置ColorList属性或者使用setPatchColor函数设置颜色，推荐前者：
ColorList属性设置颜色：
newColorList=[0.1059 0.6196 0.4667
0.8510 0.3725 0.0078
0.4588 0.4392 0.7020
0.6529 0.4059 0.3294
0.9020 0.6706 0.0078
0.6510 0.4627 0.1137
0.4000 0.4000 0.4000];
JP=joyPlot(Data,'ColorMode','Order','ColorList',newColorList);
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
setPatchColor函数设置颜色，只能设置面颜色设置不了线条颜色：
JP=joyPlot(Data,'ColorMode','Order');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
% 设置山脊颜色
newColorList=[0.1059 0.6196 0.4667
0.8510 0.3725 0.0078
0.4588 0.4392 0.7020
0.6529 0.4059 0.3294
0.9020 0.6706 0.0078
0.6510 0.4627 0.1137
0.4000 0.4000 0.4000];
JP=JP.setPatchColor(newColorList)
当然可以全部设置为同一颜色：
JP=joyPlot(Data,'ColorMode','Order','ColorList',[0,0,.6]);
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl(1))
X 每个山脊分别把X映射为颜色
JP=joyPlot(Data,'ColorMode','X','MedLine','on');
JP=JP.draw();
当然可以添加colorbar:
colorbar()
设置为其他颜色：
JP=JP.setPatchColor(winter);
JP=JP.setPatchColor(colorcube(256));
GlobalX 全局性把X坐标映射为颜色
Data={X1,X2,X3,X4,X5,X6,X7};
JP=joyPlot(Data,'ColorMode','GlobalX','MedLine','on');
JP=JP.draw();
colorbar
换成别的颜色：
JP=JP.setPatchColor(colorcube(256));
Kdensity 依靠核密度
Data={X1,X2,X3,X4,X5,X6,X7};
JP=joyPlot(Data,'ColorMode','Kdensity','MedLine','on');
JP=JP.draw();
colorbar
换成别的颜色：
JP=JP.setPatchColor(turbo);
Qt 分位染色
默认是0.25,0.75分位染色：
JP=joyPlot(Data,'ColorMode','Qt','MedLine','on');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
修改分位线(通过设置Quantiles属性)：
JP=joyPlot(Data,'ColorMode','Qt','MedLine','on','Quantiles',[.1,.9]);
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
绘制分位线(可将QtLine设置为on):
JP=joyPlot(Data,'ColorMode','Qt','MedLine','on','Quantiles',[.1,.9],'QtLine','on');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
值得一提的是，所有染色方式都可以绘制QtLine分位线：
JP=joyPlot(Data,'ColorMode','Order','MedLine','on','Quantiles',[.1,.9],'QtLine','on');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
更多分位线和更丰富配色：
JP=joyPlot(Data,'ColorMode','Qt','MedLine','on','Quantiles',[.1,.25,.75,.9],'ColorList',turbo(5),'QtLine','on');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl,{'0~0.1','0.1~0.25','0.25~0.75','0.75~0.9','0.9~1'})
更改配色：
JP=JP.setPatchColor(bone(6));
2 山脊图间距
通过设置Sep属性设置间距，例如小间距：
JP=joyPlot(Data,'ColorMode','Kdensity','Sep',1/30);
JP=JP.draw();
colorbar
间距设置为1/60:
设置大间距(1/3)：
3 绘制线状散点
只有Order类型配色不是黑色：
JP=joyPlot(Data,'ColorMode','Order','Scatter','on');
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl
Data={X1,X2,X3,X4,X5,X6,X7};
JP=joyPlot(Data,'ColorMode','GlobalX','MedLine','on','Scatter','on');
JP=JP.draw();
colorbar
4 属性单独设置
每个玩意的属性都可以单独设置
例如：
- setRidgePatch 设置山脊面
- setRidgeLine 设置山脊边缘线
- setMedLine 设置中位线
- setQtLine 设置分位线
- setScatter 设置散点
JP=joyPlot(Data,'ColorMode','Order','Scatter','on','QtLine','on','MedLine','on','Sep',1/5);
JP=JP.draw();
legendHdl=JP.getLegendHdl();
legend(legendHdl)
设置第3个山脊颜色和透明度：
JP.setRidgePatch(3,'FaceColor',[0,0,0],'FaceAlpha',.5)
循环改变所有的颜色和透明度：
for i=1:length(Data)
JP.setRidgePatch(i,'FaceColor',[1,1,1]./length(Data).*i,'FaceAlpha',.5)
end
其他玩意也都类似！
for i=1:length(Data)
JP.setRidgePatch(i,'FaceColor',[1,1,1]./length(Data).*i,'FaceAlpha',.5)
JP.setRidgeLine(i,'Color',[0,0,.8],'LineWidth',1)
JP.setScatter(i,'Color',[0,0,0,.4])
JP.setMedLine(i,'Color',[0,0,.8])
JP.setQtLine(i,'Color',[0,0,.8])
end
5 多组数据绘图
举个例子：
X1_1=normrnd(-15,2,1,20);
X1_2=[normrnd(4,4,1,10),normrnd(5,2,1,10)];
X1_3=[normrnd(6,2,1,10),normrnd(8,4,1,10)];
X1_4=[normrnd(12,1,1,10),normrnd(12,4,1,10)];
X1_5=[normrnd(-7,2,1,10),normrnd(2,4,1,10)];
X1_6=[normrnd(-7,2,1,10),normrnd(-7,4,1,10)];
Data1={X1_1,X1_2,X1_3,X1_4,X1_5,X1_6};
X2_1=normrnd(-8,2,1,20);
X2_2=[normrnd(2,4,1,10),normrnd(2,2,1,10)];
X2_3=[normrnd(18,2,1,10),normrnd(18,4,1,10)];
X2_4=[normrnd(18,1,1,10),normrnd(18,4,1,10)];
X2_5=[normrnd(5,2,1,10),normrnd(5,4,1,10)];
X2_6=[normrnd(-20,2,1,10),normrnd(-20,4,1,10)];
Data2={X2_1,X2_2,X2_3,X2_4,X2_5,X2_6};
JP1=joyPlot(Data1,'ColorMode','Order','ColorList',[12,165,154]./255,'MedLine','on','Scatter','on');
JP1=JP1.draw();
JP2=joyPlot(Data2,'ColorMode','Order','ColorList',[151,220,71]./255,'MedLine','on','Scatter','on');
JP2=JP2.draw();
% 设置中位线颜色
for i=1:length(Data1)
JP1.setMedLine(i,'Color',[12,165,154]./255)
end
for i=1:length(Data2)
JP2.setMedLine(i,'Color',[151,220,71]./255)
end
% 绘制图例
legendHdl1=JP1.getLegendHdl();
legendHdl2=JP2.getLegendHdl();
legend([legendHdl1(1),legendHdl2(1)],{'AAAAA','BBBBB'})
