设置背景颜色为透明

我的 Python 代码创建了一个阴谋条形图，但背景是白色的颜色我想把它变成透明的颜色是可行的

我的准则:

import plotly.plotly as py
from plotly.graph_objs import *
py.sign_in('username', 'api_key')
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'])])
plot_url = py.plot(data)

图表是这样的

您可以使用一个布局改变其颜色与参数 bgcolour和 opacity设置为您的愿望。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)

你可以找到一些例子 给你

最佳答案

对于一个完全透明的情节，请确保同时指定纸张 bgcolor 和情节的:

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],
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')
