I was following the example given
but facing a error:-
ValueError: Invalid property specified for object of type plotly.graph_objs.Layout: ‘colorbar’
i have tried this on local machine, google colab with plotly.version == 3.5.0
on google search i could not find any such error.
if i remove all the elements with error , then an empty plot is shown.
Hi @rohit3463,
Yeah, I’m not sure what that layout.colorbar property is doing there, but that’s not valid in recent versions of plotly.py. I opened an issue at https://github.com/plotly/documentation/issues/1250.
When I remove the colorbar property the plot seems to be working for me. I also converted it to offline mode
from plotly.offline import iplot, init_notebook_mode
import pandas as pd
init_notebook_mode()
df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/2011_february_us_airport_traffic.csv')
df.head()
df['text'] = df['airport'] + '' + df['city'] + ', ' + df['state'] + '' + 'Arrivals: ' + df['cnt'].astype(str)
scl = [ [0,"rgb(5, 10, 172)"],[0.35,"rgb(40, 60, 190)"],[0.5,"rgb(70, 100, 245)"],\
[0.6,"rgb(90, 120, 245)"],[0.7,"rgb(106, 137, 247)"],[1,"rgb(220, 220, 220)"] ]
data = [ dict(
type = 'scattergeo',
locationmode = 'USA-states',
lon = df['long'],
lat = df['lat'],
text = df['text'],
mode = 'markers',
marker = dict(
size = 8,
opacity = 0.8,
reversescale = True,
autocolorscale = False,
symbol = 'square',
line = dict(
width=1,
color='rgba(102, 102, 102)'
),
colorscale = scl,
cmin = 0,
color = df['cnt'],
cmax = df['cnt'].max(),
colorbar=dict(
title="Incoming flightsFebruary 2011"
)
))]
layout = dict(
title = 'Most trafficked US airports<br>(Hover for airport names)',
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
),
)
fig = dict( data=data, layout=layout )
iplot(fig)
Do you still get an empty plot even with this offline version?

Yes, i tried removing colorbar property it is working on the local machine but it is still showing an empty plot on google colab.
