报错：AttributeError: 'PathCollection' object has no property 'makers'

兄dei，正确的属性名称应该是 markers，而不是 makers。

请将以下行代码：

ax.scatter(xcord1, ycord1, s=30, c='red', makers='s')

改为：

ax.scatter(xcord1, ycord1, s=30, c='red', markers='s')

这样就能够解决这个错误了。

吃符号的亏，上大小写的当，细心点就没事啦！

你遇到的错误信息 "AttributeError: 'PathCollection' object has no property 'makers'" 表明你的代码中存在拼写错误。正确的属性名应该是 'markers' 而是 'makers'。

要解决这个问题，你需要 ax.scatter(xcord1, ycord1, s=30, c='red', makers='s') 这一行替换为 ax.scatter(xcord1, ycord1, s=30, c='red', markers='s')。
