Updating my graph after click a button

Dash Python
1

Hey guys,

i have some problems with my callback. I want to reset my dataframe after deleting some points of my graph. But the problem is when i do it twice or more and click on my reset button the first deleted points are shown but not the others. Therefore i have to select some points in my graph to get the other points back. I dont know where my mistake is. Here is my callback:

app.callback(
    Output("graph2","figure"),

    [Input("kind2","value"),
     Input("tab2","derived_virtual_data"),
     Input("reset","n_clicks"),
     Input("delete","n_clicks")]
     
)
def get_figure(input1,rows,clicks,kicks_all): 
    
    global n, df_input,df_input2,array,kick
    
    if clicks==None:
        clicks=0
    if kicks_all==None:
        kicks_all=0
    if clicks>n:
        n=n+1
        df_input=pd.DataFrame(df_input2)       
    if rows!=None:
        liste=[i["Time Start"] for i in rows]        
        for x in array:
            if str(x).replace(" ","T") not in liste:                
                df_input.drop(df_input[df_input["Time Start"]==x].index,axis=0,inplace=True)
    fig=px.scatter(x=df_input["Time Start"],y=df_input[input1])
    fig.update_traces( 
                      customdata=df_input.index,
                      mode='markers+text', )

    fig.update_layout(dragmode='select', hovermode=False,transition_duration=500)
    return fig

I hope you can help my. Thanks
