Charts Axis

Axes translate your data values into positions on the chart — scale type, domain, ticks, and labels are all configured per axis.

Orbital shares one axis model across bar, line, and scatter charts: define axes by id, bind series to them, and use formatters when tick text should differ from tooltip text.

• Custom tick formatting (currency, percent, compact thousands).
• Band vs linear vs log scale selection for cartesian charts.
• Multi-axis layouts (biaxial scatter) — see scatter-chart biaxial example.

• Define x_axis and y_axis as Vec<AxisDef> on any cartesian chart or container.
• Set scale_type (Band, Linear, Log, etc.) per axis.
• Attach tick_format callbacks for currency or unit suffixes on ticks.
• Cross-link from chart-type docs rather than duplicating full axis API on each page.
