如何在Plotly中调整轴标签和绘图区域之间的空间？我特别感兴趣的是减少轴标签和绘图区域之间的空间。我附上了一个示例截图。

以下是可复制的代码片段：

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go
import plotly.express as px
import pandas as pd
import numpy as np

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)

df = pd.read_csv("data.txt", sep='\t', parse_dates=["StartTimeRun", "EndTimeRun"])
df = df[df['Status'] != 'NOT_RUN']
df = df[df['Status2'] != 'NOT_RUN']

# assume you have a "long-form" data frame
# see https://plotly.com/python/px-arguments/ for more options
df_PASS = df.loc[df['Status'] == "PASS"]
df_FAIL = df.loc[df['Status'] == "FAIL"]
trace1 = go.Box(x=df_PASS["Duration(seconds)"], y=df_PASS["Keyword"], name="PASS", orientation='h', marker=dict(color='rgb(158,202,225)', line=dict(color='rgb(8,48,107)', width=1.5)))
trace2 = go.Box(x=df_FAIL["Duration(seconds)"], y=df_FAIL["Keyword"], name="FAIL", orientation='h', marker=dict(color='#fd9668', line=dict(color='rgb(8,48,107)', width=1.5)))
fig = {
    'data': [trace1, trace2],
    'layout':
    go.Layout(
        boxmode='group',  margin=dict(l=200, r=150)
    )
}

app.layout = html.Div(children=[
    html.H1(children='Hello Dash'),

    html.Div(children='''
        Dash: A web application framework for Python.
    '''),

    dcc.Graph(
        id='example-graph',
        figure=fig
    )
])

if __name__ == '__main__':
    app.run_server(debug=True)

我认为最好的方法是做fig.update_yaxes(ticksuffix = " ")技巧：

import plotly.graph_objects as go

labels = ['giraffes', 'orangutans', 'monkeys']

fig = go.Figure(go.Bar(x=[20, 14, 23], y=labels, orientation='h'))

# Adjust for your purposes the width of the blank space in "  "
fig.update_yaxes(ticksuffix = "  ")

fig.show()

不幸的是，Plotly中有no good way可以做到这一点。Plotly非常适合创建交互式情节，但代价是可调性。
我能想到的唯一的“变通方法”（也不是很好）是将绘图背景设置为与浏览器背景相同的颜色，将gridcolor更改为与浏览器背景不同的颜色，然后添加填充（在我的示例中，我假设浏览器背景是白色）。然而，这将填充x轴和y轴，我找不到解决方法。

import pandas as pd
import plotly.graph_objects as go

df = pd.DataFrame({'ColumnA':[1,2,3,4,5], 'ColumnB':[5,6,7,8,9], 'ColumnC':[6,7,8,9,10]})
trace1 = go.Box(x=df['ColumnA'],orientation='h')
trace2 = go.Box(x=df['ColumnB'],orientation='h')
trace3 = go.Box(x=df['ColumnB'],orientation='h')

fig = go.Figure(data=[trace1, trace2, trace3])
fig.update_layout(
    boxmode='group', 
    boxgap=0.25,
    boxgroupgap=0.25,
    height=500, 
    paper_bgcolor='rgba(0,0,0,0)', 
    plot_bgcolor='rgba(0,0,0,0)',
    xaxis=dict(gridcolor='lightgrey'),
    margin=dict(l=600, r=150, b=10, pad=100)
)
fig.show()

如果刻度线可以调整，并且取决于您的数据，您可以向刻度线添加空格。空格可以使用列表解析来添加，如下所示：

spaces = ' '* 25
labels = ['giraffes', 'orangutans', 'monkeys']
newLabels = [label+spaces for label in labels]

下面是一个使用刻度线和空格的例子：

import plotly.graph_objects as go
spaces = ' '* 25
labels = ['giraffes', 'orangutans', 'monkeys']

newLabels = [label+spaces for label in labels]

fig = go.Figure(go.Bar(
            x=[20, 14, 23],
            y=newLabels,
            orientation='h'))

fig.show()

实际上，你可以这样做：

fig.update_yaxes(
        title_standoff = 50
)

另一种选择是使用带有指定ticklen的外部记号，并将它们绘制为纸张颜色（甚至可能以某种方式透明？）：

import plotly.graph_objects as go

labels = ['giraffes', 'orangutans', 'monkeys']
fig = go.Figure(go.Bar(x=[20, 14, 23], y=labels, orientation='h'))
fig.update_yaxes(ticks="outside",
                 tickcolor="white",  # adjust color of the tick
                 ticklen=50  # adjust length of the tick = distance from axis
                 )

fig.show()

也适用于fig.update_xaxes。
