详细描述

GraphPointAnimation is an animation type derived from QVariantAnimation which defines how points are animated. It can make use of QVariantAnimation functionality and properties for its animations, such as duration and easing . These animations are housed inside of a QParallelAnimationGroup and hence will run in parallel.

This example shows how to use a GraphPointAnimation to set points to animate with a duration of 1000ms and easing of OutCubic:

import QtGraphs
GraphsView {
    LineSeries {
        GraphTransition {
            GraphPointAnimation { duration: 1000; easingCurve.type: Easing.OutCubic  }
        }
    }
}

For XYSeries , this is considered to be the main list of points defined inside the series. The point is linearly interpolated from the start to the end value.

注意： GraphPointAnimation currently supports animating only the last point in a series when a point is appended or removed. If a point is replaced, the animation will be triggered regardless of the point’s index within the series.
