Custom Button to Filter Plot Data

Dash Python
1

I’m trying to find a solution within Plotly/Dash where I can filter the incoming data for a plot with the selection of a custom button.

For example, consider the following data:

 x  |    y   | Special

.23     .55       N
.11     .89       Y
.45     .34       Y
.91     .21       N

How could I make an ‘updatemenu’ addition to my plots that displays only the data points where Special=‘Y’ with one button selection or all of the points with another selection’?

What I have now:


my_figure.update_layout(
                updatemenus=[
                    dict(
                        buttons=list([
                            dict(
                                args=[<unknown> (filter function goes here?)],
                                label="Only Special Data",
                                method="restyle"
                            ),
                            dict(
                                args=[<unknown> (filter function goes here?)],
                                label="All Data",
                                method="restyle"
                            )
                        ]),
                    ),
                ]
            )

I’m new to the custom button feature of Plotly so any help would be greatly appreciated!
