It seems the on_selection callback does not fire anymore. I've seen a number of open and closed issues back from 2020 discussing the usage of it, but based on the newest version 5.10.0 I cannot get anything to fire on a selection.
The simplest code example I could find (from https://github.com/plotly/plotly.py/issues/2698)
import plotly.graph_objects as go
import numpy as np
np.random.seed(1)
x = np.random.randn(500)
def on_selection_print(obj, points, selector):
print(points.point_inds)
figure_widget = go.FigureWidget(data=[go.Histogram(x=x)])
figure_widget.update_layout(dragmode="select")
figure_widget.data[0].on_selection(on_selection_print)
figure_widget.show()
Both running this in jupyter or as a python script, nothing seems to print.
I tried the latest docs on selection events but I couldn't actually get that example to run in jupyter or otherwise.
Am I just missing something simple?
Thanks!
