Tracks metric trends over time and provides visual indicators.
This class encapsulates all logic for:
- Tracking previous values of metrics
- Calculating trend directions (up/down/stable)
- Determining visual attributes (colors) for trends
- Managing enable/disable state
Example:
tracker = TrendTracker(colors_dict)
tracker.update("func1", "nsamples", 10)
trend = tracker.get_trend("func1", "nsamples")
color = tracker.get_color("func1", "nsamples")
