直方图绘制误差棒matlab,科学网—【MATLAB】如何画带errorbar的直方图叶瑞杰的博文...

(1)画竖直的errorbar

例子&＃xff1a;

close all;figure;

h&＃61;bar(volume_month_mean./1e6);       %--volume_month_mean 为12×2的矩阵

set(h,&＃39;BarWidth&＃39;,0.9);

hold on;

set(h(1),&＃39;facecolor&＃39;,[139 35 35]./255)    %--设置bar的颜色

set(h(2),&＃39;facecolor&＃39;,&＃39;k&＃39;)

ngroups &＃61; size(volume_month_mean,1);

nbars &＃61; size(volume_month_mean,2);

groupwidth &＃61;min(0.8, nbars/(nbars&＃43;1.5));

hold on;

for i &＃61; 1:nbars              %--画errorbar

x &＃61; (1:ngroups) - groupwidth/2 &＃43; (2*i-1) * groupwidth / (2*nbars);

errorbar(x,volume_month_mean(:,i)/1e6,volume_month_std(:,i)/1e6,&＃39;o&＃39;,&＃39;color&＃39;,[.5 .5 .5],&＃39;linewidth&＃39;,2);

end

for n&＃61;1:12

if n<&＃61;9

time_lab{n,1}&＃61;[&＃39;0&＃39; num2str(n)];

else

time_lab{n,1}&＃61;num2str(n);

end

end

set(gca,&＃39;XTickLabel&＃39;,time_lab,&＃39;fontsize&＃39;,14,&＃39;linewidth&＃39;,2)

ylim([-0.5 2.5])

xlim([0 13])

set(gca,&＃39;ytick&＃39;,-0.5:0.5:2.5)

(2)画水平errorbar

例子&＃xff1a;

close all;figure;

h&＃61;bar(volume_mean./1e6);           %--volume_mean是4*2的矩阵

set(h,&＃39;BarWidth&＃39;,0.9);

hold on;

set(h(1),&＃39;facecolor&＃39;,[139 35 35]./255)

set(h(2),&＃39;facecolor&＃39;,&＃39;k&＃39;)

ngroups &＃61; size(volume_mean,1);

nbars &＃61; size(volume_mean,2);

groupwidth &＃61;min(0.8, nbars/(nbars&＃43;1.5));

hold on;

for i &＃61; 1:nbars

x &＃61; (1:ngroups) - groupwidth/2 &＃43; (2*i-1) * groupwidth / (2*nbars);

errorbar(x,volume_mean(:,i)/1e6,volume_std(:,i)/1e6,&＃39;o&＃39;,&＃39;color&＃39;,[.5 .5 .5],&＃39;linewidth&＃39;,2);

end

view(-90,90)

set(gca,&＃39;xdir&＃39;,&＃39;reverse&＃39;,&＃39;ydir&＃39;,&＃39;reverse&＃39;,&＃39;XTickLabel&＃39;,{&＃39;Winter&＃39;,&＃39;Spring&＃39;,&＃39;Summer&＃39;,&＃39;Autumn&＃39;},&＃39;fontsize&＃39;,14,&＃39;linewidth&＃39;,2)

ylim([-0.5 2.5])

set(gca,&＃39;ytick&＃39;,-0.5:0.5:2.5)

ye_xylabel(gca,&＃39; &＃39;,&＃39;Volume[Sv]&＃39;)

legend(&＃39;A&＃39;,&＃39;B&＃39;,&＃39;location&＃39;,&＃39;NorthEast&＃39;)
