我们如何使用Python seaborn relplot在所有子图上绘制一条垂直线？

Question

The Python code to create the plot used is below. This creates subplots based on "variable" :

s=sb.relplot(x="timestamp",y="value",hue="variable",row="variable",
kind="line",facet_kws=dict(sharey=False),height=0.8, aspect=7,data=e)

plt.axvline(flip_timex)

s.fig.autofmt_xdate()

plt.show()

I need to add a vertical line (on a fixed date) on all the subplots generated.

plt.axvline(flip_timex) adds a vertical line only on one subplot.

Answer 1

You need to create the line in all generated plots.

grid = seaborn.relplot(...)
for ax in grid.axes.flat:
    ax.axvline(...)
