[英]Python Plotly object with legend for different marker_color
I want to add a legend for each marker_color on my second trace below but I can't figure out how to make it happen through the graph objects.我想在下面的第二条轨迹上为每个 marker_color 添加一个图例,但我不知道如何通过图形对象实现它。 Any idea?
任何想法?
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(
go.Scattergeo(
lat = df_outliers['Lat'],
lon = df_outliers['Long'],
marker = {'color' : 'grey',
'size': 5,
'symbol': 'diamond'},
name = "Stations outside clusters"
)
)
fig.add_trace(
go.Scattergeo(
lat = df_clusters['Lat'],
lon = df_clusters['Long'],
mode = 'markers',
marker_color = df_clusters['Clus_Db']
)
)
fig.update_layout(width=800, height=500,
margin=dict(r=0, b=20, l=0, t=50),
title = {
'text': "Weather Station in Canada",
'y':0.95,
'x':0.5,
'xanchor': 'center',
'yanchor': 'top' },
geo_scope='north america'
)
fig.show()
Moved around by using a for loop and specifying the type of marker when we are on the outliers value:通过使用 for 循环并在我们处于异常值时指定标记的类型来移动:
import plotly.graph_objects as go
import pandas as pd
fig = go.Figure()
for C in list(df.Clus_Db.unique()):
# Adding trace for outlier
if C==-1:
fig.add_trace(go.Scattergeo(
lat = df[df.Clus_Db == C]['Lat'],
lon = df[df.Clus_Db == C]['Long'],
name = 'Stations outside clusters',
marker = {'color' : 'grey','size': 5,'symbol': 'diamond'}
)
)
# Adding trace for clusters
else:
fig.add_trace(go.Scattergeo(
lat = df[df.Clus_Db == C]['Lat'],
lon = df[df.Clus_Db == C]['Long'],
name = 'Cluster ' + str(C))
)
fig.update_layout(width=800, height=500,
margin=dict(r=0, b=20, l=0, t=50),
title = {
'text': "Weather Station in Canada",
'y':0.95,
'x':0.5,
'xanchor': 'center',
'yanchor': 'top' },
geo_scope='north america'
)
fig.show()
