If the data could not be retrieved, this field can be used to instruct the chart to cancel the data request and log an error. Note that in most cases this field should not be used in favor of returning the correct HTTP status code (such as 404 or 500) so that the browser and any proxies do not cache the response.
Store any additional data values within this field. Although it is possible to extend the data object itself with additional fields it is not recommended to do so because a future ZoomCharts version could introduce a known parameter with the same name thus changing the behavior of an existing chart.
The unique identifier of the node.
Determines if the node data is complete (when
true) or if the data is incomplete and only provided
as a placeholder (value
In most cases this should be specified as
true, the exception being a scenario where another node contains
a link to this node, that link is included in the data response but the data for this node is not available
so a placeholder is created and the chart will have to issue another data request to load the actual data.
