Prediction Line Chart

📈 What is this?

This is a time series prediction chart. It plots both actual values and predicted values as line charts, allowing you to see if the trend is correct.

It allows you to see at a glance: Has the model captured the rhythm of data changes?

🧐 How to read?

• Blue line: Actual values.
• Green line: Predicted values.
• Overlap: If the two lines almost overlap, it indicates the model is super accurate!
• Deviation: If the blue line is above and the green line is below, it indicates the model always underestimates.

🛠️ How to use?

Note: This chart has a lasso function for selecting abnormal parameters.

• Find lag: If the green line is always slow, it indicates the model is slow to react.
• Check sudden changes: If the blue line suddenly jumps but the green line doesn't respond, it indicates the model hasn't seen this situation before.
