在2条曲线之间填充区域MATLAB

问题描述

如果我有3个向量:均值，均值+标准差和均值标准差，如何填充均值+标准差和均值标准差之间的空间并使第三个矢量均值"可见?我这样尝试过

If i have 3 vectors: mean, mean+standard deviation and mean-standard deviation, how can I fill the space between mean+standard deviation and mean-standard deviation and keep visible the third vetor "mean"?I tried like this

h1 = area(x,y_m);
h2= area(x,y_std1);
h3= area(x,y_std2);

，但以均值+标准差填充整个空间.在该代码中，y_m = mean; y_std1 =平均值+标准差； y_std2 =平均标准偏差.这些向量是从excel导入的.

but it fills the entire space under mean+standard deviation.In that code, y_m=mean; y_std1=mean+standard deviation; y_std2=mean-standard deviation. These vectors are imported from excel.

推荐答案

像这样的东西可能会提供您想要的东西

Something like this may provide what you are looking

% random data
x = 0:0.1:10;
y = sin(x);
ystd = ones(size(x))*1;
y_std1 = y+ystd;
y_std2 = y-ystd;

figure
fill([x fliplr(x)],[(y_std1) fliplr(y_std2)],'r'); hold on
plot(x,y)
