Fill Configuration

The fill tab controls how polygon features are colored. Four fill types are available:

Gradient

Color features along a color ramp based on a numeric data property from the vector tiles.

  1. Select a property — choose which attribute in the tile data drives the color (e.g. population, area, index).
  2. Choose a palette — pick from 20+ built-in palettes organized into categories:
    • Sequential — single-hue ramps (e.g. Blues, Greens, Oranges).
    • Diverging — two-hue ramps centered on a midpoint (e.g. Red–Blue, Purple–Green).
    • Color-blind safe — palettes designed for accessibility.
    • Multi-color — rainbow and spectral palettes.
    • Special — purpose-built palettes (e.g. terrain, temperature).
  3. Set opacity — control the transparency of the fill (0–100%).
  4. Customize stops (optional) — edit individual gradient stop values and colors to fine-tune the ramp.

Legend

When using a gradient fill, you can optionally display a legend overlay on the map:

  • Show legend — toggle the legend on or off.
  • Include layer title — show the layer name above the legend.
  • Include field description — show the property name below the title.

Property Selector

If the layer has multiple numeric properties suitable for gradient coloring, you can enable a property selector dropdown that appears on the runtime map. This lets report viewers switch the gradient property without reopening the catalog dialog. When the property changes, gradient stops are proportionally recalculated to the new property's value range.

Single Color

Apply a uniform fill color to all features.

  • Color — pick any color using the color picker.
  • Opacity — set fill transparency (0–100%).

Rule-Based

Define rules that map attribute values to colors. Each rule specifies:

  • Property — the vector-tile attribute to evaluate.
  • Operator — one of: equals, not equals, contains, starts with, ends with.
  • Value — the value to match.
  • Color — the color to apply when the rule matches.

Rules are evaluated in order. The first matching rule wins. Features that don't match any rule use a default fallback color.

A rule-based legend is also available, showing each rule's color and label.

None

Disable the fill entirely. Features have no fill color — only outlines, labels, or extrusion may be visible.
