如何在MATLAB中绘制带有标准偏差值的误差线图?

问题描述

对于 MATLAB ，我是一个非常陌生的人，期待逐步解决方案.我有数据series(y)，必须针对(x)进行绘制.另外，我还具有(y)的每个数据点的标准偏差值.现在，我必须绘制这些系列以突出显示误差线.我该怎么办?

I am very new to MATLAB and expect a step-by-step solution. I have data, series(y), which I have to plot against (x). Also I have the standard deviation values for each data point of (y). Now I have to plot these series highlighting the error bars. How can I do that?

数据在文本文件中，按列排序:

The data is in a text file sorted in columns as:

X = -50, -49, -48, -47....0....1, 2, 3, 4, 5....till 50

Y = 1.2, 1.0, 1.1, 1.9, 1.3.....

标准偏差= 0.6, 0.5, 0.3, 0.6, 0.6.....

此外，如何控制这些图形的刻度和外观属性?

Also, how do I control the ticks and appearance property for these kinds of graphs?

推荐答案

x = 1:0.1:10;
y = sin(x);
e = 0.1 * randn(length(x), 1);

errorbar(x,y,e)

set(gca, 'Xlim', [4 10])
set(gca, 'XTick', 4:2:10)

有关其他属性的更改，另请参见get(gca)和get(gcf).

See also get(gca) and get(gcf) for other properties to change.

例如，要获取有关任何这些功能的帮助，请执行help errorbar.

For help on any of these functions, do, for example, help errorbar.
