Solve the following python programming problem given the following code:
def __init__(self, df, figure, x, y, title = 'Scatter Plot', description = 'Scatter Plot', init_params = { 
    
}, route_func = None) : 
    self.plot_opts = { 
        'title' : title, 
        'description' : description, 
        'x_accessor' : 'x', 
        'y_accessor' : 'y', 
        'init_params' : init_params, 
} 
    figure.graphics.chart_type ('point') 
    figure.graphics.target (('#' + figure.chart_id)) 
    for (k, v) in list (figure.get ().items ()) : 
        self.plot_opts [k] = df 
if (not route_func) : 
        def get_data() : 
            args = { 
                
} 
            for c in init_params : 
                if request.args.get (c) : 
                    args [c] = request.args [c] 
else : 
                    args [c] = init_params [c] 
return jsonify (ScatterPlot.to_json (self.apply_filters (df, args), x, y)) 
route_func = get_data 
super (ScatterPlot, self).__init__ (figure.chart_id, figure.url, self.plot_opts, route_func) 

    
    

    Fix the buggy line: self.plot_opts [k] = df
assistant
#Here is Python code to fix the buggy line: self.

self.plot_opts [k] = v
