更改组barplot中的颜色

Question

我正在绘制带有错误栏的分组栏。就像现在一样，酒吧不是黄色就是蓝色。我想改变一下：每个组内的酒吧应该仍然有不同的颜色，但我想选择比黄色和蓝色还要别的东西。这怎么能做到？

model_series = [0.74*100, 0.5*100; 0.74*100, 0.5*100;0.74*100, 0.5*100 ]; 
model_error = [4.8,5.9;0, 0; 0,6]; 

%subplot(2,1,1) 

h = bar(model_series); 
set(h,'BarWidth',1); % The bars will now touch each other 
set(gca,'YGrid','on') 
set(gca,'GridLineStyle','-') 
%set(h,'FaceColor',[0.2,0.5,0.3]) 
set(gca,'YLim',[0 100]) 
title(['\fontsize{16}Accuracies']) 

set(gca,'xtick',[1 2 3 4 5 6]) 
set(gca,'xticklabel',{'\fontsize{16}1.condition','\fontsize{16}2.condition','\fontsize{16}3.condition'}) 
set(get(gca,'YLabel'),'String','\fontsize{16}Accuracy') 

hold on; 
numgroups = size(model_series, 1); 
numbars = size(model_series, 2); 
groupwidth = min(0.8, numbars/(numbars+1.5)); 
legend('\fontsize{16}Group1','\fontsize{16}Group2','\fontsize{16}Group3') 

for i = 1:numbars 
    % Based on barweb.m by Bolu Ajiboye from MATLAB File Exchange 
    x = (1:numgroups) - groupwidth/2 + (2*i-1) * groupwidth/(2*numbars); % Aligning error bar with individual bar 
    errorbar(x, model_series(:,i), model_error(:,i), 'k', 'linestyle', 'none'); 
end

要更改的属性确实是'FaceColor'我看到在你的代码注释掉。你写它就像set(h,'FaceColor',[0.2,0.5,0.3])这改变了所有酒吧的'FaceColor'。如果你需要不同的颜色为每个酒吧，你需要分配不同的颜色，他们每个人是这样的：

set(h(1), 'FaceColor', 'm'); %Changing color of first bar to magenta 
set(h(2), 'FaceColor', 'g'); %Changing color of second bar to green

随着MATLAB R2014b及更高版本中，您还可以使用dot notation访问/修改属性。

h(1).FaceColor = 'm';   %Changing color of first bar to magenta 
h(2).FaceColor = 'g';   %Changing color of second bar to green
