向绘图图形的每个方面添加跟踪

Question

我想在情节情节的所有方面添加痕迹。例如，我想在显示 15% 小费的“小费”数据集的散点图的每个日常方面添加一条参考线。但是，我在下面的尝试仅将行添加到第一个方面。import plotly.express as pximport plotly.graph_objects as goimport numpy as npdf = px.data.tips()ref_line_slope = 0.15 # 15% tip for referenceref_line_x_range = np.array([df.total_bill.min(), df.total_bill.max()])fig = px.scatter(df, x="total_bill", y="tip",facet_col="day", trendline='ols')fig = fig.add_trace(go.Scatter(x=reference_line_x_range,y=ref_line_slope*reference_line_x_range,name='15%'))fig.show()

Answer 1

根据plotly 的示例，您可以'all'作为row和col参数传递，甚至可以跳过空的子图：

fig.add_trace(go.Scatter(...), row='all', col='all', exclude_empty_subplots=True)

Answer 2

这不是一个优雅的解决方案，但它应该适用于大多数情况

for row_idx, row_figs in enumerate(fig._grid_ref):

    for col_idx, col_fig in enumerate(row_figs):

        fig.add_trace(go.Scatter(...), row=row_idx+1, col=col_idx+1)
