如何在 plotly 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)

这给出了气泡 plot 并且它不显示标签。 如何添加标签请帮助 ] 1

您的[data5]更适合用作go.Figure() object。

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

这是对图形标签的参考： 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 - 在这里给出一个通用的提示，类似下面的东西应该可以工作：

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