Try it:

Usage sample

fill(keys, angle, mode, opacity)

Linear gradient fill.

Detailed description

There are three modes:

ObjectBoundingBox preserving an angle
ObjectBoundingBox no angle preservation
UserSpaceOnUse

Modes:

ObjectBoundingBox preserving an angle
If boolean is passed it says how gradient behaves, specificaly how gradient line angle behaves. If true - it is ObjectBoundingBox with angle preservation. If angle is preserved, in any shape angle looks as one expects it to see.
Note: By default gradient vector for any shape, which sides are not in 1:1 proportions, will not look as expected, because browser transforms this angle.

ObjectBoundingBox no angle preservation
If false is passed - that's ObjectBoundingBox no angle preservation. In this case default behaviour comes up - gradient vector is calculated for a shape with 1:1 side proportions.

UserSpaceOnUse
If anychart.graphics.math.Rect is passed - that'sUserSpaceOnUse mode. In this mode gradient gets its own size and coordinates. Shapes with such gradient will be colored only in those parts, which are covered by this custom gradient. Read more about this mode at gradientUnits. Angle is always preserved in this mode.

Description: a) ObjectBoundingBox no angle preservation.
b) ObjectBoundingBox preserving an angle.
c) UserSpaceOnUse.
d) Three step gradients.

Params:

Name	Type	Description
keys	Array.<(anychart.graphics.vector.GradientKey\|string)>	Gradient keys.
angle	number	Gradient angle.
mode	boolean \| anychart.graphics.vector.Rect \| Object	Gradient mode.
opacity	number	Gradient opacity.

Returns:

anychart.core.ui.Background - Self instance for method chaining.

Try it:

Usage sample

fill(keys, cx, cy, mode, opacity, fx, fy)

Radial gradient fill.

Params:

Name	Type	Description
keys	Array.<(anychart.graphics.vector.GradientKey\|string)>	Color-stop gradient keys.
cx	number	X ratio of center radial gradient.
cy	number	Y ratio of center radial gradient.
mode	anychart.graphics.math.Rect	If defined then userSpaceOnUse mode, else objectBoundingBox.
opacity	number	Opacity of the gradient.
fx	number	X ratio of focal point.
fy	number	Y ratio of focal point.

Returns:

anychart.core.ui.Background - Self instance for method chaining.

Usage sample

listen

listen(type, listener, useCapture, listenerScope)

Adds an event listener to an implementing object.

Detailed description

The listener can be added to an object once, and if it is added one more time, its key will be returned.
Note Notice that if the existing listener is one-off (added using listenOnce), it will cease to be such after calling the listen() method.

Params:

Name	Type	Default	Description
type	string		The event type id.
listener	function(Object e)		Callback method. Function that looks like `function(event){ // event.actualTarget - actual event target // event.currentTarget - current event target // event.iterator - event iterator // event.originalEvent - original event // event.point - event point // event.pointIndex - event point index }`.
useCapture	boolean	false	Whether to fire in capture phase. Learn more about capturing https://javascript.info/bubbling-and-capturing
listenerScope	Object		Object in whose scope to call the listener.

Returns:

Object - Unique key for the listener.

Try it:

Usage sample

listenOnce

listenOnce(type, listener, useCapture, listenerScope)

Adds an event listener to an implementing object.

Detailed description

After the event is called, its handler will be deleted.
If the event handler being added already exists, listenOnce will do nothing.
Note In particular, if the handler is already registered using listen(), listenOnce() will not make it one-off. Similarly, if a one-off listener already exists, listenOnce will not change it (it wil remain one-off).

Params:

Name	Type	Default	Description
type	string		The event type id.

Detailed description

Note: When stroke properties are set both by complex stroke object properties and by stroke() method params, object properties have priority. E.g. setting shape.stroke('10 red', 5); (or shape.stroke({color: 'red', thickness: 10}, 5); will result in a red stroke with thickness 10px.
