Setting Background color to transparent in Plotly plots

For a fully transparent plot, make sure to specify both the paper bgcolor and the plot's:

import plotly.plotly as pyfrom plotly.graph_objs import *py.sign_in('', '')data = Data([    Bar(        x=['Sivaranjani S', 'Vijayalakshmi C', 'Rajeshwari S', 'Shanthi Priscilla', 'Pandiyaraj G', 'Kamatchi S', 'MohanaPriya', 'Madhumitha G', 'Franklin Alphones Raj J', 'Akfaris Almaas', 'Biswajit Champati', 'Priya R', 'Rekha Rajasekaran', 'Sarath Kumar B', 'Jegan L', 'Karthick A', 'Mahalakshmi S', 'Ragunathan V', 'Anu S', 'Ramkumar KS', 'Uthra R'],        y=[1640, 1394, 1390, 1313, 2166, 1521, 1078, 1543, 780, 1202, 1505, 2028, 2032, 1769, 1238, 1491, 1477, 1329, 2038, 1339, 1458],        text=['Scuti', 'Scuti', 'Cygni', 'Scorpii', 'Scuti', 'Pollux', 'Scorpii', 'Pollux', 'Scuti', 'Pollux', 'Scorpii', 'Scorpii', 'Scuti', 'Cygni', 'Scorpii', 'Scuti', 'Scuti', 'Pollux', 'Scuti', 'Pollux', 'Pollux']    )])layout = Layout(    paper_bgcolor='rgba(0,0,0,0)',    plot_bgcolor='rgba(0,0,0,0)')fig = Figure(data=data, layout=layout)plot_url = py.plot(fig, filename='transparent-background')

You can use the a Layout to change its colours with the parameters bgcolour and opacity set to yours desires. You could do something like:

data = Data([Bar(... The same you already have...)])layout = Layout(    title='Your Title',    (xaxis, yaxis, WHAT EVER YOU WANT TO SET)    paper_bgcolor='rgb(233,233,233)', # set the background colour)fig = Figure(data=data, layout=layout)py.plot(fig)
