【研究工具】Matlab画带状图函数

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);
