[line-timeseries-rolling] Time Series with Rolling Average Overlay

[MarkusNeusinger]

A time series plot showing raw data with a smoothed rolling average (moving average) line overlaid, useful for trend identification.

[claude]

✅ Spec ID: line-timeseries-rolling

Rationale: This plot combines time series visualization with a rolling average overlay for trend identification - distinct from line-timeseries (basic) and line-confidence (uncertainty bands).

Add label approved to begin generation.

line-timeseries-rolling: Time Series with Rolling Average Overlay

Description

A time series plot that displays raw data points alongside a smoothed rolling average (moving average) line. The raw data shows actual observations while the rolling average reveals underlying trends by reducing noise and short-term fluctuations. This dual-layer visualization is essential for trend identification, making patterns visible that might be obscured by day-to-day volatility.

Applications

• Analyzing stock price movements with a moving average to identify buy/sell signals and trend reversals
• Monitoring website traffic or user engagement metrics with smoothed trends for seasonal pattern detection
• Tracking sensor data (temperature, humidity) with noise reduction to reveal true environmental trends

Data

• date (datetime) - Timestamp values representing points in time
• value (numeric) - Raw measurements or observations at each timestamp
• rolling_avg (numeric) - Computed rolling average (e.g., 7-day, 30-day window)
• Size: 50-500 points (enough data for meaningful rolling window calculation)
• Example: Daily stock closing prices with 20-day moving average, hourly temperature readings with 24-hour rolling mean

Notes

• Use a lighter, semi-transparent style for raw data (thin line or markers with alpha)
• Display the rolling average as a prominent, smooth line in a contrasting color
• Include a legend clearly distinguishing "Raw Data" from "Rolling Average (N-day)"
• Consider showing the window size in the legend or title (e.g., "7-Day Rolling Average")
• Grid lines on both axes improve readability of underlying values
• The rolling average line will be shorter than raw data due to window requirements
