-    \example qmlsurfacelayers
-    \title Qt Quick 2 Surface Multiseries Example
-    \ingroup qtdatavisualization_examples
-    \brief Using multiple series with Surface3D in a QML application.
-
-    The Qt Quick 2 surface example shows how to make a 3D surface plot displaying 3 layers using
-    Surface3D with Qt Quick 2.
-
-    \image qmlsurfacelayers-example.png
-
-    The focus in this example is on generating a multiseries surface plot from 3 different height
-    map images, so in this section we skip explaining the application creation. For a more detailed
-    QML example documentation, see \l{Qt Quick 2 Scatter Example}.

-    \section1 Adding Data to the Graph
-
-    This example shows how to add several surface series to one graph using using
-    HeightMapSurfaceDataProxies and how to control their visibilities individually.
-
-    Let's start by creating a specific gradient for each layer:
-
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 0
-
-    Then we'll create the series themselves. It happens simply by adding 3 separate Surface3DSeries
-    to the Surface3D graph as children:
-
-    \dots 0
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 1
-    \dots 0
-
-    You'll notice we added the created gradients to the \c baseGradient properties of the series.
-    We could have added them to the \c baseGradients property of the Theme3D in Surface3D instead,
-    but doing it this way ensures each gradient is applied to a correct series:
-
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 2
-    \dots
-
-    \section1 Controlling the Graph
-
-    Let's add some checkboxes to control the visibility of layers:
-
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 3
-
-    We don't need to do anything on the \c onCheckedChanged as we bound the \c checked state to
-    the \c visible property of the series directly:
-
-    \dots 0
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 4
-    \dots 0
-
-    Let's add some more checkboxes to control how the layers are displayed, when visible:
-
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 5
-
-    In addition to these we have three buttons, one of which is of special interest to us. It is
-    used to control whether we want to slice into only one layer, or all of them:
-
-    \snippet qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 6
