我正在尝试使用 plotly 来比较回归模型的系数，使用误差条作为置信区间。我使用下面的代码来绘制它，使用变量作为y散点图中的分类轴。问题是这些点是重叠的，我想像在设置barmode='group'. 如果我有一个数字轴，我可以手动躲避它们，但我做不到。

fig = px.scatter(
        df, y='index', x='coef', text='label', color='model',
        error_x_minus='lerr', error_x='uerr',
        hover_data=['coef', 'pvalue', 'lower', 'upper']
    )
fig.update_traces(textposition='top center')
fig.update_yaxes(autorange="reversed")

在此处输入图像描述

使用构面，我几乎得到了我想要的结果，但是一些标签偏离了情节并且不可见：

fig = px.scatter(
    df, y='model', x='coef', text='label', color='model',
    facet_row='index',
    error_x_minus='lerr', error_x='uerr',
    hover_data=['coef', 'pvalue', 'lower', 'upper']
)
fig.update_traces(textposition='top center')
fig.update_yaxes(visible=False)
fig.for_each_annotation(lambda a: a.update(text=a.text.split("=")[-1]))

在此处输入图像描述

有人对在第一种情况下躲避点或在第二种情况下显示标签有任何想法或解决方法吗？

提前致谢。

PS：这是我为生成图而制作的随机假数据框：

您的第二次尝试非常接近可行的解决方案。只需为您的标签腾出更多空间：

height=600, width=800

'OLS'然后将标签放置在每个子图的边界内命名的轨迹的标签：

fig.for_each_trace(lambda t: t.update(textposition='bottom center') if t.name == 'OLS' else ())
