在下面的代码中,我有标记标签,这些标记现在靠近这些标记。在标记与其标签之间进行自定义目标的方法是什么?我现在想将标签离标记稍远一些。
import plotly.express as px
import plotly.graph_objs as go
import pandas as pd
rows=[['501-600','15','122.58333','45.36667'],
['till 500','4','12.5','27.5'],
['more 1001','41','-115.53333','38.08'],
]
colmns=['bins','data','longitude','latitude']
df=pd.DataFrame(data=rows, columns=colmns)
df = df.astype({"data": int})
fig=px.scatter_geo(df,lon='longitude', lat='latitude',
color='bins',
opacity=0.5,
size='data',
projection="natural earth")
fig.update_traces(hovertemplate ='bins')
fig.add_trace(go.Scattergeo(lon=df["longitude"],
lat=df["latitude"],
text=df["data"],
textposition="middle right",
mode='text',
showlegend=False))
fig.show()
我看到您正在使用第二个Scattergeo
跟踪来显示标签。这似乎不是一个坏主意,因为在我看来,fig.add_annotation
在px.scatter_geo
图中可能有些棘手。因此,我只需稍微调整纬度和经度数即可将标签放置在您喜欢的位置,例如lon=[float(d) + 10 for d in df['longitude']]
