| 14 | \brief The GraphAnimation type is the base type for all animations for 2D Qt Graphs series. |
| 15 | |
| 16 | GraphAnimation is based on VariantAnimation and provides an interface for interpolation for child animations. |
| 17 | This type is an abstract type and doesn't have any default implementation for interpolation. Its derived types |
| 18 | should be used for the respective animations, such as GraphPointAnimation, SplineControlAnimation. |
