I encountered a strange error when using adtk's plot method: ValueError: Multi-dimensional indexing (e.g. obj[:, None]) is no longer supported. Convert to a numpy array before indexing instead

My code is:
`
df = pd.read_csv('cleaned_data/原始值-周均价.csv')
df['date'] = pd.to_datetime(df['date'])
df.set_index('date',inplace=True)
df = validate_series(df)
from adtk.data import validate_series
from adtk.visualization import plot
from adtk.transformer import RollingAggregate
from adtk.transformer import DoubleRollingAggregate
from adtk.detector import ThresholdAD
threshold_ad = ThresholdAD(high=10, low=5)
anomalies = threshold_ad.detect(df)
plot(df, anomaly=anomalies, ts_linewidth=1, ts_markersize=3, anomaly_markersize=5, anomaly_color='red', anomaly_tag="marker");
`
I encountered an error:
`

My version information：
adtk==0.6.2
I have made the following solutions, but none of them can be solved:
- I asked chatgpt, and it told me to switch to an array, but although I knew that the plot method required df, I still tried an array, and it was really an error.
