Line chart

Line charts connect data points with lines, making them useful for showing trends, changes, or comparisons over time. They can also be combined with bars for dual-axis visuals that highlight relationships between two measures.

Template options

1. Simple line → plots one or more series across a continuous axis.

2. Combo (bar + line) → overlays a line series on top of bars to compare different measures in the same chart.

Mapping options

For line charts

• X → Dimension for the horizontal axis (often time or ordered categories).

• Y → Measure for the vertical axis (line height).

• Color → Splits lines into series.

• Label → Annotates points with text.

For combo (bar + line)

• Cols → Dimension for the horizontal axis (shared by both bar and line).

• Bar

  • Y → Measure for bar height.

  • Color (optional) → Splits bars into series.

• Line

  • Y → Measure for the line.

  • Color (optional) → Splits lines into series.

Tips

1. Line charts work best with continuous or ordered categories (e.g. time, sequence, ranking).

2. Avoid too many series (over 5–6) to keep lines readable.

3. Use combo charts when you want to highlight the relationship between two measures, such as volume (bars) and rate (line).
