（1）画竖直的errorbar
例子：
close all;figure;
h=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 = size(volume_month_mean,1);
nbars = size(volume_month_mean,2);
groupwidth =min(0.8, nbars/(nbars+1.5));

hold on;
for i = 1:nbars             %--画errorbar
      x = (1:ngroups) - groupwidth/2 + (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=1:12
      if n<=9
         time_lab{n,1}=[&#39;0&#39; num2str(n)];
      else
         time_lab{n,1}=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：
close all;figure;
h=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 = size(volume_mean,1);
nbars = size(volume_mean,2);
groupwidth =min(0.8, nbars/(nbars+1.5));

hold on;
for i = 1:nbars
      x = (1:ngroups) - groupwidth/2 + (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;)
