整理了一个画带状图（Ribbon）的函数。
% function: drawRibbon-Draw Ribbon Plot for Given Data (average & confidence interval)
%
% input paras
% arrData: average data of each group; size[m(length of each group)*n(number of group);
% arrConfData: confidence data of each group; size[m(length of each group)*n(number of group);
% cellColor: color of each group;
% cellGroupNames: legend for each group;
% alphaRibbon: alpha of the Ribbon;
function drawRibbon(arrData,arrConfData,cellColor,cellGroupNames,alphaRibbon)
[dataLength, numGroup] = size(arrData);
xData =1:dataLength;
% calculate upper & lower limit for filled area and draw
for indGroup = 1 : numGroup
arrUpper = arrData(:,indGroup) + arrConfData(:,indGroup);
arrLower = arrData(:,indGroup) - arrConfData(:,indGroup);
fill([xData xData(end:-1:1)],[arrUpper' arrLower(end:-1:1)'],'k','FaceColor',cellColor{indGroup},'FaceAlpha',alphaRibbon,'EdgeColor','none')
hold on;
end
% draw average data
for indGroup = 1 : numGroup
arrFig(indGroup) = plot(xData,arrData(:,indGroup),'-','Color',cellColor{indGroup},'lineWidth',1,'markersize',10);
hold on;
end
% xlabel('xlabel','FontSize',12);
% ylabel('ylabel','FontSize',12);
% axis([0 0 0 0]);
legend(arrFig,cellGroupNames);
hold off;
end
使用示例
figure(1);
drawRibbon([meanHappy meanSad],[confHappy confSad],{[192/255,44/255,56/255],[122/255,115/255,116/255]},{'Happy','Sad'},0.3);
