Question

我试图在情节上绘制一些NFL球队，但是每当我一直试图对某些球队进行注释时，文字就会移到情节的角落，而我无法靠近实际数据点。 / p>

参考：https://plot.ly/python/text-and-annotations/#styling-and-coloring-annotations

我已经尝试了超过半小时的时间来更改x和y值，无论我什么时候都将盒子移到绘图的角落，并且我无法在美国地图内找到它。

这是我的代码和情节：

import pandas as pd
import numpy as np
from IPython.display import IFrame
import plotly.plotly as py

%matplotlib inline

df = pd.DataFrame({'latitude': [42.7,25.9,42.1,40.8],
                  'longitude': [-78,-80,-71,-74],
                  'color': range(4)})


annotations=[
        dict(
            x=-74,
            y=40.8,
            xref='latitude',
            yref='longitude',
            text='Patriots',
            showarrow=True,
            font=dict(
                family='Courier New, monospace',
                size=16,

            bgcolor='#ff7f0e',
            opacity=0.8
        )
    ]

marker = dict(
    size = 8,
    opacity = 0.8,
    reversescale = True,
    autocolorscale = False,
    symbol = 'square',
    line = dict(
        width=1,
        color='rgba(102, 102, 102)'
    ),
    colorscale = 'Jet',
    cmin = 0,
    color = df['color'],
    cmax = 4,
    colorbar=dict(
        title="NFL Teams"
    )
)

geo = dict(
    scope='usa',
    projection=dict( type='albers usa' ),
    showland = True,
    landcolor = "rgb(250, 250, 250)",
    subunitcolor = "rgb(217, 217, 217)",
    countrycolor = "rgb(217, 217, 217)",
    countrywidth = 0.5,
    subunitwidth = 0.5
)

data = [ dict(
        type = 'scattergeo',
        locationmode = 'USA-states',
        lon = df['longitude'],
        lat = df['latitude'],
        text = 'text' ,
        mode = 'markers',
        marker = marker
        )]

layout = dict(
        title = '',
        colorbar = True,
        annotations= annotations,
        geo = geo
    )

fig = dict( data=data, layout=layout )
py.iplot( fig, validate=False, filename='file1' )

结果图如下：
