Evolution of Commits with EMA and RSI

This widget offers a detailed visual representation of the historical evolution of commits.

The purple bars reflect the absolute values of commits made in specific periods, providing a clear view of the activity.

For a smoother interpretation, the blue bars reveal the Exponential Moving Average (EMA) of commits, emphasizing trends over time.

Additionally, a green line is incorporated to represent the Relative Strength Index (RSI), a key indicator used in various sectors.

In the context of Git development, the RSI offers insight into the team's fitness in terms of the frequency of commits.

Both EMA and RSI act on the last 4 samples, providing a more accurate view of recent trends.

Benefits and Possible Interpretations:
  • Trend Identification: The EMA provides a smoothed representation of commit trends over time, aiding in the identification of overarching patterns in the team's contribution.
  • Strength of Development Momentum: The RSI serves as an indicator of the team's development momentum.
  • Decision Support for Planning: The combination of EMA and RSI aids in decision-making for future development planning.

Overall, this type of chart serves as a powerful tool for project managers, team leads, and developers alike, offering insights that contribute to informed decision-making, improved collaboration, and efficient resource utilization in the Git development environment.
