Overview
Line charts are primarily used to visualize trends and changes over time (time-series data). They are effective for showing continuous data and identifying patterns, cycles, or anomalies.
Key Features
- X-axis: Typically represents time or an ordered sequence.
- Y-axis: Represents a quantitative value.
- Multiple Lines: Can be used to compare trends across different categories.
Best Practices
- Don't clutter the chart with too many lines.
- Use consistent time intervals on the x-axis.
- Use annotations to highlight significant events or turning points.
