I have been trying to connect the markers in a line graph to get a better idea of the shape of a curve. The following is the code:

# Plot the data for each month in separate figures
for month in months:
    month_data = monthly_data[monthly_data['month'] == month]
    plt.figure(figsize=(40, 20))
    plt.plot(month_data['datetime'], month_data['Transaction_Amount'], marker='o', linestyle='-')
    plt.title(f'Transaction Amount - Month {month}')
    plt.xlabel('Timestamp')
    plt.ylabel('Transaction Amount')
    plt.grid(True)
    plt.show()

I tried adding a separate line which would use the markers as the connecting points but it didn’t work.
