10 inherited items
clonedFrom

Type $type.Optional <this>Inherited from BaseObject

Reference to the original object this object was cloned from. We need to keep this so we can disassociate it from source object when this object is disposed.

config

Type objectInherited from BaseObject

Use this property to set JSON-based config. When set, triggers processing routine, which will go through all properties, and try to apply values, create instances, etc.

Use this with caution, as it is a time-consuming process. It's used for initialchart setup only, not routine operations.

An SVG <group> element hold primitive (effect) definitions.

filterUnits

Which units are used when drawing filter.

Use "userSpaceOnUse" when applying filters on a perfectly straight line.

height

Type numberDefault 120Inherited from Filter

Height of the filter element in percent.

If the filter is designed to "bleed out" of the original target element, like for example a shadow, you need this bigger than 100, or the non-fitting parts will be clipped.
