matplotlib 图中点的标签 [英] Label for point in plots in matplotlib

问题描述

所以这是一个关于已发布解决方案的问题.我试图在我拥有的matplotlib散点图中的点上放置一些数据标签.我试图模仿这里的解决方案:

So this is sort of a question about a posted solution. I was trying to put some data labels on points in a matplotlib scatterplot I have. I was trying to imitate the solution here:

是否有与 MATLAB 的 datacursormode 等效的 matplotlib?

在 def __call __(自身，事件)内:我在以下行失败:

xdata, ydata = event.artist.get_data()
AttributeError: 'CircleCollection' object has no attribute 'get_data'

在此处查看文档: http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.artist

我看不到 Artist 的方法 get_data().这只是已经过时的东西还是我错过了什么?如果有的话，有人知道如何获得等效呼叫吗?

I see no method get_data() for Artist. Is this just something that has been deprecated or did I miss something? If it has been, anyone know of how else to get an equivalent call?

推荐答案

如果您查看 __call__ 中的其余代码，您将看到 xdata 和 ydata 从未使用过.您只需删除该行

If you look at the rest of the code in __call__ you'll see xdata and ydata are never used. You can simply delete the line

xdata, ydata = event.artist.get_data()

Joe 的其他漂亮代码运行良好.

and the rest of Joe's beautiful code works just fine.
