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.

Edge cases

Numeric range, irregular structure, and data volume

Exercise numeric range, sparse structure, and large inputs with valid data. Each tab materializes data only when needed and never silently repairs invalid values.

Wide numeric range

Mix zero, very small finite values, and very large finite values to verify automatic domains, precision, and stable geometry. NaN and Infinity remain intentionally invalid. It applies 2 data-integrity rules that preserve finite values and axis domains.

It applies 6 high-volume rules for deterministic generation and bounded output. This family materializes 60,000 logical events and bounds rendered bar marks at 12,000.

Extreme environments

Reconfigure for display, input, and device capability

Combine container size, input method, display capability, and user preference instead of guessing a device name. Compare mobile, watch, e-paper, monochrome, dot-matrix, and standards-based extreme environments on the same chart.

Fluid responsive

Reflow axes, legends, descriptions, and controls from the available container size.

Legend and emphasis

Identify series, emphasize a datum or range, place a custom callout, and let readers select marks.

Legend: Explain the series and scale represented by each color, line, or symbol inside the chart.
Point and range highlights: Emphasize a datum, value set, axis interval, or plot region without changing source values.
Custom callouts: Attach user-authored safe text to a datum, axis range, or normalized plot position. 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.
Interactive selection: Click a mark to select it, press Escape to clear it, and consume selection state and events in the host application.
