如何设置绘图的背景颜色和网格线的颜色?

问题描述

这是我的代码:

导入 plotly.graph_objectsfig = go.Figure()fig.add_trace(go.Bar(name='第 1 组',x=['Var 1', 'Var 2', 'Var 3'], y=[3, 6, 4],error_y=dict(type='data', array=[1, 0.5, 1.5]),宽度=0.15))fig.add_trace(go.Bar(名称='第 2 组',x=['Var 1', 'Var 2', 'Var 3'], y=[4, 7, 3],error_y=dict(type='data', array=[0.5, 1, 2]),宽度=0.15))fig.update_layout(barmode='组')图.show()

输出:

2. 背景自定义

Here is my code:

import plotly.graph_objects as go

fig = go.Figure()
fig.add_trace(go.Bar(
    name='Group 1',
    x=['Var 1', 'Var 2', 'Var 3'], y=[3, 6, 4],
    error_y=dict(type='data', array=[1, 0.5, 1.5]),
    width=0.15
))
fig.add_trace(go.Bar(
    name='Group 2',
    x=['Var 1', 'Var 2', 'Var 3'], y=[4, 7, 3],
    error_y=dict(type='data', array=[0.5, 1, 2]),
    width=0.15
))
fig.update_layout(barmode='group')
fig.show()

output:

I read this but code from seems depreciated and does not works.

Question: How to set background color of the plot and color for grid lines?

解决方案

This should help

import plotly.graph_objects as go
from plotly.graph_objects import Layout

# Set layout with background color you want (rgba values)
# This one is for white background
layout = Layout(plot_bgcolor='rgba(0,0,0,0)')

# Use that layout here
fig = go.Figure(layout=layout)
fig.add_trace(go.Bar(
    name='Group 1',
    x=['Var 1', 'Var 2', 'Var 3'], y=[3, 6, 4],
    error_y=dict(type='data', array=[1, 0.5, 1.5]),
    width=0.15
))
fig.add_trace(go.Bar(
    name='Group 2',
    x=['Var 1', 'Var 2', 'Var 3'], y=[4, 7, 3],
    error_y=dict(type='data', array=[0.5, 1, 2]),
    width=0.15
))
fig.update_layout(barmode='group')

# Change grid color and axis colors
fig.update_xaxes(showline=True, linewidth=2, linecolor='black', gridcolor='Red')
fig.update_yaxes(showline=True, linewidth=2, linecolor='black', gridcolor='Red')
fig.show()
