2D Plot Mode
The 2D plot mode displays a single row or column of a surface map as a curve. This is useful for examining how values change along one axis while keeping the other axis position fixed.
Controls
| Control | Description |
|---|---|
| Row/Column toggle | Switch between plotting rows or columns |
| Row/Column slider | Select which row or column to display |
| Uniform/Scaled toggle | Switch between uniform and scaled grid |
| Selection mode | Rectangular or linear selection |
| Grid lines | Toggle grid line visibility |
| Display mode | Lines and points, lines only, or points only |
| Scale factors | Adjust line thickness and point marker size |
Grid Scaling
- Uniform grid — all data points are equally spaced regardless of axis values. Useful when axis values are clustered or repeated.
- Scaled grid — data point spacing reflects actual axis values. Provides a mathematically accurate view.
Editing in 2D Mode
You can select and edit data points directly on the 2D plot:
- Click a point to select it, or drag to select a range
- Use the standard editing commands (Ctrl+E, Ctrl+R, Ctrl+P, etc.)
- Changes are immediately reflected in the Grid and 3D views
The 2D view always shows the current values regardless of the display mode setting in the Grid view.
Reading the Plot
The plot header shows:
- The map name
- The axis name and value for the currently selected row/column
The plot uses the inner axis as the horizontal axis, with values on the vertical axis.
