In theory, a chart can contain multiple overlaid DataTransform objects. This allows you to display a chart with multiple data sets rendered in the same area but with different ranges. For example, you might want to show monthly revenues compared to the number of units sold. If revenue was typically in millions while units was typically in the thousands, it would be difficult to render these effectively along the same range. Overlaying them in different DataTransform objects allows the end user to compare trends in the values when they are rendered with different ranges.
Charts can only contain one set of DataTransform.
Most of the time, you will use the ChartBase object, which hides the existance of the DataTransform object between the chart and its contained glyphs and axis objects. If you create your own ChartElement objects, you must understand the methods of the DataTransform class to correctly implement their element.

of event. | EventDispatcher | |
![]() |
Indicates whether an object has a specified property defined. | Object | |
![]() |
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | |
![]() |
Indicates whether the specified property exists and is enumerable. | Object | |
![]() |
