show_anomalies for multivariate #2114

Open SaltedfishLZX opened 11 months ago

SaltedfishLZX commented 11 months ago

Hi, I've experimented with the anomaly detection example, and it has proven to be exceptionally helpful in saving me a significant amount of time while establishing the anomaly detection test. I do have a question:

I am currently engaged in multivariate forecasting and wish to conduct anomaly detection on individual components. To achieve this, I have employed component_wise=True for the scorer, and it has been effective. However, when attempting to utilize show_anomalies (which gives visually appealing result figures), all the results are put into a single figure, making it challenging to discern individual results. I have been unable to identify a method to plot each variable separately. Could you provide guidance on this matter?Thanks！

Hi @SaltedfishLZX,

This feature is not yet implemented, I added it to the roadmap.

If you have time and would like to contribute to Darts, feel free to tackle it ! :)
