[英]Plotly: How to plot specific rows on Bubble Map?
如何使用 Plotly 对 ZA7F5F35426B5628741 使用 Map plot 某个状态的大小? (即:plot 仅限西海岸和东海岸州)
我看过 Plotly 的例子,但没有给出太多解释如何重现相同的 plot (https://plotly.com/python/bubble-maps/#united-states-bubble-map )
样本数据:
state latitude longitude mag
0 Alabama 34.7360 -85.629000 4.8
1 Alaska 71.1404 -131.232000 7.9
2 Arizona 36.9940 -109.058700 5.3
3 Arkansas 36.4400 -89.920000 5.0
4 California 41.9780 -115.366000 7.3
我的代码:
every_earthquake = pd.read_csv('earthquake_states.csv')
fifty_state_quakes = every_earthquake[['state', 'latitude', 'longitude', 'mag']].dropna()
state_mag_max = pd.DataFrame(fifty_state_quakes, columns=['state',
'latitude', 'longitude', 'mag']).dropna()
state_max_mag_df = state_mag_max.groupby(['state'])['latitude', 'longitude','mag'].max().reset_index()
state_max_mag_df['text'] = state_max_mag_df['state'] + '<br>Magnitude ' + (state_max_mag_df['mag']).astype(str)
magnitude = [(0,1), (2,3), (4,5), (5,6), (7,8), (9, 10)]
colors = ['royalblue','crimson','lightseagreen','orange','lightgrey']
scale = 0.45
fig = go.Figure()
for i in range(len(magnitude)):
magn = magnitude[i]
state_max_mag_df1 = state_max_mag_df[(state_max_mag_df['mag'] >= magn[0]) & (state_max_mag_df['mag'] < magn[1])]
fig.add_trace(go.Scattergeo(
locationmode = 'USA-states',
lon = state_max_mag_df['latitude'],
lat = state_max_mag_df['latitude'],
text = state_max_mag_df['text'],
marker = dict(
size = state_max_mag_df['mag']/scale,
color = colors,
line_color = 'rgb(40,40,40)',
line_width = 0.5,
sizemode = 'area'),
name = '{0} - {1}'.format(magn[0], magn[1])))
fig.update_layout(
showlegend = True,
geo = dict(scope = 'usa',
landcolor = 'rgb(217, 217, 217)',
))
fig.show()
Output 我得到:
