Had to add one folder to the examples structure so
installation works correctly.

+    \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 ../examples/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 ../examples/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 ../examples/qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 2
+    \dots
+
+    \section1 Controlling the graph
+
+    Let's add some checkboxes to control the visibility of layers:
+
+    \snippet ../examples/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 ../examples/qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 4
+    \dots 0
+
+    Let's add some more checkboxes to control how the layers are displayed, when visible:
+
+    \snippet ../examples/qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 5
+
+    In addition to these we have two 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 ../examples/qmlsurfacelayers/qml/qmlsurfacelayers/main.qml 6
