Chart View

The chart view supports multiple chart types using tabs across the top: XY, Histogram, Box Plot, KDE, and Heatmap.

Press c from the main view to open the chart.

  • Plot style: Line, Scatter, or Bar (cycle with ↑/↓ or ←/→ when focused).
  • X axis: Search for and select a numeric or temporal column (single selection).
