I want to arrange the graphs vertically in plotly.

I would like to arrange several graphs in a row in plotly, but I can't move them because of an error.

The program summary reads all CSVs in the folder and divides each CSV into two.The fig.add_trace appears twice in the for statement because you want the split csv to be superimposed and displayed as a single graph.
Then, I want to create graphs for the number of csvs in the for statement and arrange them vertically.

x_axis="G"
y_axis="D"
graphNumber = 11
file_names=glob.glob('*.csv')

def get_colorpalette(colorpalette, file_number):
    palette=sns.color_palette(
        colorpalette, file_number)
    rgb = ['rgb({}, {}, {})'.format(*[x*256 for x in rgb])
           for rgb in palette]
    return rgb

colors=get_colorpalette('hls',graphNumber')
config=make_subplots(len(df_list_1), 1)

for i in range(len(df_list_1)):
    for jin range (graphNumber):
        print(i)
        config.add_trace(
            go.Scatter(
                x=df_list_0[i][x_axis][parts_number*j:parts_number*(j+1)], 
                y=df_list_0[i][y_axis][parts_number*j:parts_number*(j+1)], 
                name = 'forward {:1f}'.format(j*0.1),
                marker={'color':colors[j]}, mode='lines'
            ), i, 1
        )
        
        config.add_trace(
            go.Scatter(
                x=df_list_1[i][x_axis][parts_number*j:parts_number*(j+1)],
                y=df_list_1[i][y_axis][parts_number*j:parts_number*(j+1)], 
                name = 'backward {:1f}'.format(j*0.1),
                marker={'color':colors[j]}, mode='lines'
            ), i, 1
        )
config.update_xaxes(matches='x')
config.show()

The reason is that i is i in the fig.add_trace(...,i,1) section as shown in the error message Note:the starting cell is (1,1).

Therefore, for i in range(len(df_list_1)): must be for i in range(1,len(df_list_1)+1): or fig.add_trace(...,i+1,1).
