For a fully transparent plot, make sure to specify both the paper bgcolor and the plot's:
对于完全透明的绘图，请确保同时指定纸张 bgcolor 和绘图的：
import plotly.plotly as py
from 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],

)
])
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 bgcolourand opacityset to yours desires. You could do something like:
您可以使用布局通过参数更改其颜色bgcolour并opacity根据您的需要进行设置。你可以这样做：
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)
you can find some examples here
