matlab绘制散点图标记

在MATLAB中，可以使用scatter函数绘制散点图，并使用text函数在散点上添加标记。

例如，假设有以下数据：

x = randn(50,1);
y = randn(50,1);
labels = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};

使用scatter函数绘制散点图：

scatter(x,y)

添加标记：

text(x,y,labels)

完整代码：

x = randn(50,1);
y = randn(50,1);
labels = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};

scatter(x,y)
text(x,y,labels)
