GrainPattern – amCharts 5 Documentation

Type class

Grain pattern.

Allows to add grain (noise) effect to your Graphics objects.

Note, grain pattern does not support fill and color setting.

Use colors setting to define colors of a grain pixels.

Note, rotation setting is not supported by this pattern.

GrainPattern can be used (imported) via one of the following packages.

// Import GrainPattern
import * as am5 from "@amcharts/amcharts5";

// Create GrainPattern
am5.GrainPattern.new(root, {
  // ... config if applicable
});

<!-- Load GrainPattern -->
<script src="index.js"></script>

Inheritance

GrainPattern extends Pattern.

GrainPattern is not extended by any other symbol.

Settings

Set these settings on a GrainPattern object using its set() and setAll() methods.

Read about settings concept.

animations #	Type `Array` Inherited from `IEntitySettings` Animations the element plays on its own, described as data - so they can be set from a JSON config and saved with it. Each one animates a setting of the element (or, with `target: "dataItem"`, a value of its data item - a map point's `positionOnLine`, say). They start when the setting is applied, restart when it changes, and stop when the element is disposed. A saved config keeps what was configured, never a value caught half way through an animation. sprite.set("animations", [ { key: "rotation", to: 360, duration: 4000, loops: 0 }, { key: "scale", from: 1, to: 1.3, duration: 800, loops: 0, yoyo: true, easing: "sine" } ]); @since 5.20.8
color #	Type `Color` Inherited from `IPatternSettings` Color of the pattern shape. Click here for more info
colorOpacity #	Type `undefined` \| `number` Inherited from `IPatternSettings` Opacity of the pattern shape. Click here for more info
colors #	Type `Array` Default `[color(0x000000)]` An array of colors to randomly use for pixels.
density #	Type `undefined` \| `number` Default `1` Density of noise. Value range: `0` (no noise applied) to `1` (noise is applied to every pixel). The bigger the value, the higher chance that pixel will have another pixel painted over with random opacity from `minOpacity` to `maxOpacity`.
fill #	Type `Color` Inherited from `IPatternSettings` Color to fill gaps between pattern shapes. Click here for more info
fillOpacity #	Type `undefined` \| `number` Default `1` Inherited from `IPatternSettings` Opacity of the fill for gaps between pattern shapes. Click here for more info
height #	Type `undefined` \| `number` Default `50` Inherited from `IPatternSettings` Height of the pattern tile, in pixels. Click here for more info
horizontalGap #	Type `undefined` \| `number` Default `0` Horizontal gap between noise pixels measured in `size`.
id #	Type `undefined` \| `string` Inherited from `IEntitySettings` A unique ID for looking the element up in `root.entitiesById`. Setting an ID that another element already has throws an error.
ignoreThemes #	Type `undefined` \| `false` \| `true` Default `false` Inherited from `IEntitySettings` Ignores themes: no theme rule applies to the element, not even one of the default theme. @since 5.15.6
maxOpacity #	Type `undefined` \| `number` Default `0.2` Maximum opacity of a noise pixel.
minOpacity #	Type `undefined` \| `number` Default `0` Minimum opacity of a noise pixel.
repetition #	Type `"repeat"` \| `"repeat-x"` \| `"repeat-y"` \| `"no-repeat"` Default `"repeat"` Inherited from `IPatternSettings` How pattern tiles are repeated when filling the area. Click here for more info
rotation #	Type `undefined` \| `number` Default `0` Inherited from `IPatternSettings` Rotation of pattern in degrees. Supported values: -90 to 90. Click here for more info
size #	Type `undefined` \| `number` Default `1` Size of a grain in pixels.
stateAnimationDuration #	Type `undefined` \| `number` Default `0` Inherited from `IEntitySettings` How long, in milliseconds, a switch from one state to another animates. `0` switches at once.
stateAnimationEasing #	Type `$ease.Easing` Default `out(cubic)` Inherited from `IEntitySettings` Easing of the animated switch from one state to another.
strokeDasharray #	Type `number[]` \| `number` Inherited from `IPatternSettings` Stroke (border or line) dash settings. Click here for more information
strokeDashoffset #	Type `undefined` \| `number` Inherited from `IPatternSettings` Stroke (border or line) dash offset. Click here for more information
strokeWidth #	Type `undefined` \| `number` Default `1` Inherited from `IPatternSettings` Width of the pattern's line elements.
themeTags #	Type `Array` Inherited from `IEntitySettings` Tags that theme rules can target. They also count for the element's children, so a rule can match a child by a tag of its parent. Click here for more info
themeTagsSelf #	Type `Array` Inherited from `IEntitySettings` Tags that theme rules can target, like `themeTags`, but only for this element, not its children. Click here for more info
themes #	Type `Array` Inherited from `IEntitySettings` Themes applied to the element and everything inside it.
userData #	Type `any` Inherited from `IEntitySettings` Any data of your own to keep with the element.
verticalGap #	Type `undefined` \| `number` Default `0` Vertical gap between noise pixels measured in `size`.
width #	Type `undefined` \| `number` Default `50` Inherited from `IPatternSettings` Width of the pattern tile, in pixels. Click here for more info

Methods
