TypeError: missing a required argument: 'y'

[gible]

Hello everyone,
I am trying to plot a graph from the result of LSTM anomaly.

fig, ax = plt.subplots(figsize=(16,12))
ax.plot(pd.to_datetime(df['datetime']), df['power'], color='b', label='Normal')
ax.scatter(only_power,  label='Anomaly', marker='o')
ax.xaxis_date()
plt.xlabel('Date Time')
plt.ylabel('power')
plt.legend()
fig.autofmt_xdate()
plt.show()

This code gives me a plot which is attached below.

I also have a list only_power which lie on blue line -- df['power'].

I want to show this 'only_power' list on blue line with red color but whenever I used my code I get missing y axis error.

How can I solve this problem, so that I can show 'only_power' list with red color in df['power'] line (blue line )
