下面是相关的脚本片段:

t = dict(family="Univers LT Std", size=14,color='black')

# figure setup
fig = go.Figure(data=[go.Scatter(x=name, y=thing, type='scatter')])

fig.update_layout(yaxis=dict(title="<i>Deviation from median (%)</i>",
                             titlefont=t, tickfont=t,gridcolor='rgba(255, 255, 255, 0.2)', showgrid=True))

如何在不更改任何其他字体属性的情况下将轴上的文本 apple, ball, cat 的文本样式更改为斜体

Answer 1

Plotly 允许一些 HTML styling直接在轴标签的字符串输入上。并且您可以轻松更改thing = ["apple","ball","cat"]至['<i>apple</i>', '<i>ball</i>', '<i>cat</i>']使用列表理解 thing = ['<i>'+elem+'</i>' for elem in thing]

代码:

import plotly.graph_objs as go

thing = ["apple","ball","cat"]
thing = ['<i>'+elem+'</i>' for elem in thing]

name = [1,2,3]
t = dict(family="Univers LT Std", size=14,color='black')

fig = go.Figure(data=[go.Scatter(x=name, y=thing, type='scatter')])

fig.update_layout(yaxis=dict(title="<i>Deviation from median (%)</i>",
                             titlefont=t, tickfont=t,gridcolor='rgba(255, 255, 255, 0.2)', showgrid=True))
fig.show()
