# class for extracting information from the plotly.graph_object Figure()
class TraceInfo:
    def __init__(self, figure):
        self.fig = figure
        self.traces = self.__traces()
        self.number = self.__len__()
        self.names = self.__trace_names()
        self.colors = self.__trace_colors()

    def __getitem__(self, index):
        return self.traces[index]

    def __len__(self):
