子图-同色条

Question

我有两个轮廓子图，分别带有Z数据。我只希望有一个涵盖两个比例尺的颜色条。请参阅下面的照片，了解现在的情况。我不知道如何在python中执行此操作。我主要熟悉Matlab。如果您有任何建议，请告诉我。

import pandas as pd 
from plotly.graph_objs import *
import plotly.tools as tools
from plotly.subplots import make_subplots
import plotly.graph_objects as go

PPFD_6in = pd.read_csv('MasterData.csv') 

Pow50 = PPFD_6in['P50']
Pow100 = PPFD_6in['P100']
x_data = PPFD_6in['X'] / 12
y_data = PPFD_6in['Y'] / 12

# Pow50.describe()
# Pow100.describe()

fig = tools.make_subplots(rows=1, cols=2, shared_yaxes=True)

fig.add_trace(go.Contour(x=x_data,y=y_data,z=Pow50,            
            contours=dict(
            coloring ='heatmap',
            showlabels = True, 
            labelfont = dict( 
                size = 12,
                color = 'white',
            )
        )
        ),row=1, col=1)

fig.add_trace(go.Contour(x=x_data,y=y_data,z=Pow100,            
            contours=dict(
            coloring ='heatmap',
            showlabels = True, 
            labelfont = dict( 
                size = 12,
                color = 'white',
            )
        )
        ),row=1, col=2)


fig.show()
