Editor colours

Tuning Editor gives you two ways to control colour in the map editor: the Heatmap, which shades table cells by value, and the Editor Colours palette, which sets the colours used for curves, surfaces, grids and so on across every editor. Both apply live to all open views.

The heatmap

In the Table view the Heatmap toolbar button shades each cell according to its value, so hot and cold regions of a map stand out at a glance. Click the button to toggle it on or off; click the ▾ next to it for its settings.

Figure 1

The Heatmap Settings dialog has:

• Value range — Auto uses each map’s own min and max, while Manual lets you set Min and Max yourself so several maps can be read on one common scale.
• Opacity — how strongly the shading tints the cells (this is not used in the 2D plot).
• Also colour axis cells — extend the shading to the axis header cells (in the 2D view this is labelled “Also colour axis labels”).

Changes take effect immediately, so the dialog only has a Close button.

The Editor Colours palette

The Colours… button on the 2D plot and 3D surface toolbars opens Editor Colours, the application-wide colour palette. Every open editor shares it, so a change here is reflected everywhere at once.

Figure 2

Each row is a colour role with a clickable swatch; click a swatch to pick a new colour. A swatch marked (default) is still using the theme’s colour, and Restore defaults clears your overrides so every role falls back to its theme default. The roles are grouped into a tab per editor:

2D plot

• Data, Reference and Diff — the current curve, the comparison curve and their difference.
• Background, Grid and Axis — the plot surround.
• Selection and Active cell — the current selection and cell.
• Diff (positive), Diff (negative), Map region (data) and Map region (axis) — the difference and map-region highlights.

2D file editor

• Density background, Density thumb and Density map accent — the colours of the density overview strip.

3D surface

• Data, Reference, Diff, Background, Grid, Axis, Selection and Active cell — as on the 2D plot, applied to the surface.
• Wireframe — the surface mesh lines.

Hex editor

• Background, Grid, Selection, Active cell, Sparkline, Text and Address text — the hex grid and its text.
• Density background, Density thumb and Density map accent — the density strip.
• Diff (positive), Diff (negative), Diff (highlight), Map region (data) and Map region (axis) — the difference and map-region highlights.

Tip — set a Manual heatmap range when you want to compare several maps on the same scale; and if a palette experiment goes wrong, Restore defaults puts every colour back.
