Graph selectedData update

Dash Python
2

Hello BSen. Welcome to the Dash Community! To do what you’re wanting to do here you would likely want to use to use dcc.State in your callback along these lines.

@app.callback(Output('graph1', 'figure'),
               [Input('graph2', 'selectedData')],
              [State('graph1', 'figure')])
def update_graph1(selected_data, figure):
    figure['layout'] = [whatever you want to change]
    return figure

However if your graphs are plotting a lot of data this will be costly in terms of performance. I would recommend looking into this post. Especially this response to help with that.

Best of luck to you BSen!
