0 数据准备

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};

数据为多个一维向量放在元胞数组中，大概像这样：

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

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)endfor 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'})
