|---|---|
| ControlTemplate |
A ControlTemplate object.

This example illustrates how to create custom bar models.
To do this, create an object that represents a custom model of a particular series (CustomBar2DModel) and assign it to the Model property of a corresponding series type (BarSeries2D.Model).
Then, create the ControlTemplate object which contains all necessary visual elements to create your own custom model. Assign this template to the PointTemplate property of a series custom model (CustomBar2DModel.PointTemplate).
