问题描述
我想创建一个条形图,在其中更改一些条形的颜色.我的条形图的代码如下:
I'd like to create a bar graph where I change the color of some bars. The code for my bar graph is the following:
y = [0.04552309, -0.001730885, 0.023943445, 0.065564478, 0.032253892, 0.013442562, ...
-0.011172323, 0.024595622, -0.100614203, -0.001444697, 0.019383706, 0.890249809];
bar(y)
我希望前 6 个条形为黑色,后 6 个条形为蓝色,但我不知道该怎么做.
I want the first six bars to be black and the last 6 bars to be blue, but I have no idea how to do it.
推荐答案
您需要分别绘制它们(但在相同的轴上):
You need to plot them separately (but on the same axes):
bar(1:6,y(1:6),'k')
hold on
bar(7:numel(y),y(7:end),'b')
set(gca,'xtick',1:numel(y))
