如何在 Python 3 中将数据点悬停在 Plotly 的折线图中时一次显示数据点及其标签？

Question

我想在 PLOTLY 的折线图中添加数据点及其各自的标签，将其悬停时可见。

import plotly.plotly as py
import plotly.graph_objs as go

data = [
    go.Scatter(
        x = [1,2,3,4,5],
        y = [2,1,6,4,4],
        text = ["Text A", "Text B", "Text C", "Text D", "Text E"],
        hoverinfo = 'text',
        marker = dict(
            color = 'green'
        ),
        showlegend = True,textposition='top center'
    )
]

py.iplot(data, filename = "add-hover-text")

然后我做了 hoverinfo = 'y'，显示像，

我已经编写了代码，但它显示的不是数据点就是文本中定义的标签。我想同时展示两者。你能帮我一次显示数据点和它的标签吗？

Answer 1

只需将您的 hoverinfo = 'text', 更改为 hoverinfo = 'text+y',

hoverinfo 帮助指出：

The 'hoverinfo' property is a flaglist and may be specified
as a string containing:
  - Any combination of ['x', 'y', 'z', 'text', 'name'] joined with '+' characters
    (e.g. 'x+y')
    OR exactly one of ['all', 'none', 'skip'] (e.g. 'skip')
  - A list or array of the above
