小提琴图不适用于 python-plotly 中的负值

Question

我正在尝试使用 python 中的 plotly 绘制交互式小提琴图，但它不适用于负值。

如果您运行此代码，输出 (out.html) 不会显示任何内容。如果您删除所有“-”字符（甚至只是其中的几个），小提琴图将出现在显示正值的输出中。

import plotly
import numpy as np

outputFile = 'out.html'

没有错误信息。我期望 out.html 显示带有负值的小提琴图。

Answer 1

我不确定您为什么选择禁用验证，但如果您启用它，接下来的错误会让您了解您的配置有什么问题。

具体来说：

span配置不正确，请删除或修复
x 应该是 x0 而不是
