Surface3D QML 类型

描述了 3D 表面图的用法。更多...

导入语句	import QtDataVisualization 1.7
自	QtDataVisualization 1.0
继承	AbstractGraph3D

所有成员列表，包括继承成员

属性

axisX : ValueAxis3D
axisY : ValueAxis3D
axisZ : ValueAxis3D
flipHorizontalGrid : bool (since QtDataVisualization 1.2)
selectedSeries : Surface3DSeries
seriesList : list

方法

void addSeries(Surface3DSeries series)
void removeSeries(Surface3DSeries series)

详细描述

此类型使开发者能够使用 Qt Quick 渲染 3D 表面图。

您需要导入数据可视化模块才能使用此类型

import QtDataVisualization 1.2

之后您就可以在您的 qml 文件中使用 Surface3D

import QtQuick 2.0
import QtDataVisualization 1.2
