如何在图中添加标签？

Question

x2016 = data[data.year == 2016].iloc[:20,:]
num_students_size  = [float(each.replace(',', '.')) for each in x2016.num_students]
international_color = [float(each) for each in x2016.international]
trace1 = go.Scatter(
x = x2016.world_rank,
y = x2016.teaching,
mode = "markers",
marker=dict(
color = international_color,
size = num_students_size,
showscale = True
),
text = x2016.university_name
)
data5 = [trace1]
iplot(data5)

这给出气泡图，并且不显示标签。如何添加标签，请帮忙] 1

您的[data5]更适合作为go.Figure()对象。

下面有一个很好的顺序：https://plotly.com/python/line-and-scatter/#bubble-scatter-plots

以下是图形标签的引用： https://plotly.com/python/figure-labels/

fig.update_layout(
    title="Plot Title",
    xaxis_title="x Axis Title",
    yaxis_title="y Axis Title",
    font=dict(
        family="Courier New, monospace",
        size=18,
        color="#7f7f7f"
    )
)

fig.show()

所以-为了在此处给出一般性提示，应执行以下操作：

data5 = go.Figure(data=trace1,
    title="Plot Title",
    xaxis_title="x Axis Title",
    yaxis_title="y Axis Title"
)
iplot(data5)
