Hello :),

I’m trying to catch the legend selection in a pie chart and this return me None.
I tried to do to the same with the legend of a scatter plot and it was ok .

Here is what I tried :

@app.callback(
             Output('seletedItem','children'),
              [Input('pie_chart','restyleData')])
def getSelectedLegend(selected):
       print(selected)
       raise PreventUpdate

Anyone can help me ?
