在绘图中按顺序标记点 [英] Labeling points in order in a plot

问题描述

我有两个向量，分别表示要绘制的点(x，y)的位置.

I have two vectors representing the location of points (x,y) that I'd like to plot.

我知道如何绘制它们，但我也想用在图中可见的标签来标记它们1、2、3、4....标签代表它们在向量中的顺序.

I know how to plot them, but I'd also like to label them 1, 2, 3, 4... with labels visible on the plot. The labels represent their order in the vector.

推荐答案

这里是执行此操作的一种方法:

Here's one way to do this:

p = rand(10,2);
labels = cellstr( num2str([1:10]') );  %' # labels correspond to their order

plot(p(:,1), p(:,2), 'rx')
text(p(:,1), p(:,2), labels, 'VerticalAlignment','bottom', ...
                             'HorizontalAlignment','right')
