Control help

Zoom and pan inspect the rendered surface without changing data axes or values. When playback controls are available, they move through real steps in the order each unique value first appears in the source data.

Use Tab to reach a control and Enter or Space to activate it. With the chart focused, use plus and minus to zoom and arrow keys to pan.

Auto placement compares perimeter candidates and avoids the plot, legend, and other callouts when possible. Explicit placement is preserved with only necessary safety correction. Callout text wraps safely inside the bubble. Long unbroken tokens are visually shortened within the line budget, while the complete source text remains available to assistive technology.
