如何解决Plotly无法在Python中的Latex标签中显示文本
我正在用plotly做一些绘图。我需要在轴的标签中使用数学符号。绘图显示乳胶部分，但不显示文本部分：
import plotly.graph_objects as go
import numpy as np
x = np.array([1,2,3,4,5,6,7,8,9])
fig = go.figure()
fig.add_trace(
go.Scatter(
x = x,y = x**2,)
)
fig.update_layout(
title = 'My figure',xaxis_title = r'$\Delta t$ (s)',yaxis_title = r'This text is not displayed/$\sqrt{2}$ (ps)',)
fig.show()
产生
请注意，标签中的文本部分未显示。我正在将Python 3.8.5与Plotly 4.9.0结合使用，并在Ubuntu 20.04中使用Firefox 81.0.2查看该图。
解决方法
我也遇到了同样的问题。临时解决方案是引用 \textrm 中的文本。即
fig.update_layout(
title = 'My figure',xaxis_title = r'$\Delta t\textrm{(s)}$',yaxis_title = r'This text is not displayed/$\sqrt{2}\textrm{(ps)}$',)
结果如下所示。
