Chart years and axis bounds

Year and Y-axis settings can be placed in chartpack defaults, a section or a chart.

Limit one chart

- chart:
    title: Near-term real GDP
    start_year: 2025
    end_year: 2035
    y_axis:
      min: -5
      max: 10
    series:
      - variable: GDPR(USA)

Both years must exist in the projections and end_year must not precede start_year. Bounds must be finite, with max no lower than min.

Override one inherited bound

- section:
    start_year: 2025
    end_year: 2050
    y_axis:
      min: -10
      max: 10
- chart:
    y_axis:
      max: 25
    series:
      - variable: GDPR(USA)

This chart keeps the section’s min: -10 and uses its own max: 25. Omit an automatic bound; do not set it to null.
