Properties
adapter # |
Type Inherited from Holds Adapter. |
---|---|
animations # |
Type Inherited from A list of |
categories # |
Type Inherited from An object containing categories. |
clonedFrom # |
Type Inherited from 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 Inherited from 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. |
dataContext # |
Type Inherited from Sets to a reference to an original object from Component's data. A reference to an original object in Component's data, that this Data Item is derived from. |
dates # |
Type Inherited from An object containing dates. |
depth # |
Type Inherited from Depth of the Data Item. In nested data structures, like TreeMap, this indicates the level this data point is at, in relation to the parent Data Item. |
events # |
Type Inherited from An |
hasProperties # |
Type Default Inherited from Indicates whether Data Item has any properties set. If it does not have any, the code can use this property to check whether they need to apply costly operation of re-applying properties, whenever Data Item-related element is redrawn, e.g. series. |
Type Inherited from Sets hidden flag for data item. Mostly used to initially hide data item. Returns |
|
id # |
Type Inherited from Sets the user-defined id of the element. |
ignoreMinMax # |
Type Inherited from Sets whether this data point should not be included in the scale and minimum/maximum calculations. Exclude from min/max calculations? E.g. some we may want to exclude a particular data point from influencing |
index # |
Type Inherited from Data Item's position index in Component's data. |
isHiding # |
Type Default Inherited from Indicates whether Data Item is currently animiting from visible to hidden state. |
isTemplate # |
Type Default Inherited from Identifies if this object is a "template" and should not be treated as real object that is drawn or actually used in the chart. |
locations # |
Type Inherited from An object containing locations for the Data Item. A location is a position within date or category, or, in some other cases, where there is no single point but rather some period. Click here for info how data item locations work |
opacity # |
Type Inherited from Sets opacity for all Data Item's related elements (Sprites). |
parent # |
Type Inherited from When we are using a nested data structure, like for example in a TreeMap, this property points to a parent Data Item of this one. |
properties # |
Type Inherited from An object containing Data Item specific appearance properties in key-value pairs. Sometimes a single Data Item needs to apply different properties than the rest of the data That's where Data Item's Please note that you should set Data Item-specific properties using |
sprites # |
Type Default Inherited from A list of E.g. an Data Item keeps track of all of them, so it can toggle all related visual elements when it itself is toggled. |
uid # |
Type Inherited from Returns object's internal unique ID. |
values # |
Type Inherited from An object containing calculated values. |
visible # |
Type Inherited from Sets visibility of the Data Item. Returns |
workingLocations # |
Type Inherited from Current working locations. |
