Question

So, I have this app in which i create a figure using plotly.express.line and then I use the add_selection() function like that : figure.add_selection( x0=0, y0=10, x1=10, y1=0 ) which indeed adds a selection box. But, the issue is that I want to remove this selection box by script. I tried a lot of things like figure.update_layout(dragmode= zoom ) but even this doesn t remove the selection box. Is there any functions like figure.clear_selection() or something like that ? Thanks a lot :)

import numpy as np
from plotly import graph_objects as go


def clear_selection(self):
    """
    Custom function for cleaning selections from Plotly Figure

    """
    if  selections  in self[ layout ]:
        self[ layout ][ selections ] = ()


go.Figure.clear_selection = clear_selection

# Normal plot, adding selection and looping through for user to interact with selection
t = np.linspace(0, 4*np.pi)
fig = go.Figure()
fig.add_scatter(
    x=t,
    y=np.sin(t),
)

for ii in range(5):
    fig.clear_selection()
    fig.add_selection(
        x0=ii, y0=-0.5,
        x1=ii+1, y1=0.75
    )
    fig.show()
    breakpoint()
