SplineSeries QML Type▲
-
Import Statement: import QtCharts 2.4
-
Inherits:: XYSeries
-
Instantiates:: QSplineSeries
Detailed Description▲
A spline series stores the data points and the segment control points needed by QPainterPath to draw a spline. The control points are automatically calculated when the data changes. The algorithm computes the points so that the normal spline can be drawn.
The following QML code shows how to create a simple spline chart:
ChartView {
title: "Spline"
anchors.fill: parent
antialiasing: true
SplineSeries {
name: "SplineSeries"
XYPoint { x: 0; y: 0.0 }
XYPoint { x: 1.1; y: 3.2 }
XYPoint { x: 1.9; y: 2.4 }
XYPoint { x: 2.1; y: 2.1 }
XYPoint { x: 2.9; y: 2.6 }
XYPoint { x: 3.4; y: 2.3 }
XYPoint { x: 4.1; y: 3.1 }
}
