-    \title Bars Example
-    \ingroup qtdatavisualization_examples
-    \brief Using Q3DBars in a widget application.
-
-    The bars example shows how to make a 3D bar graph using Q3DBars and combining the use of
-    widgets for adjusting several adjustable qualities. The example shows how to:
-
-    \list
-        \li Create an application with Q3DBars and some widgets
-        \li Use QBar3DSeries and QBarDataProxy to set data to the graph
-        \li Adjust some graph and series properties using widget controls
-        \li Select a row or a column by clicking an axis label
-    \endlist
-
-    It also demonstrates how having negative bar values affects the graph.
-
-    For instructions about how to interact with the graph, see \l{Qt Data Visualization Interacting with Data}{this page}.
-
-    \image bars-example.png
-
-    \include examples-run.qdocinc
-
-    \section1 Creating the Application
-
-    First, in main.cpp, we create a QApplication, instantiate Q3DBars and a window container
-    for it:
-
-    \snippet bars/main.cpp 0
-
-    The call to QWidget::createWindowContainer is required, as all data visualization graph classes
-    (Q3DBars, Q3DScatter, Q3DSurface) inherit QWindow. Any class inheriting QWindow cannot be used
-    as a widget any other way.
-
-    Then we'll create horizontal and vertical layouts. We'll add the graph and the vertical
-    layout into the horizontal one:
-
-    \snippet bars/main.cpp 1
-
-    We're not using the vertical layout for anything yet, but we'll get back to it in
-    \l {Using widgets to control the graph}
-
-    Next, let's create another class to handle the data addition and other interaction with the
-    graph. Let's call it \c GraphModifier (See \l {Setting up the graph} and
-    \l {Adding data to the graph} for details):
-
-    \snippet bars/main.cpp 2
-
-    The application main is done and we can show the graph and start the event loop:
-
-    \snippet bars/main.cpp 3
-
-    \section1 Setting up the Graph
-
-    Let's set up the graph in the constructor of the \c GraphModifier class we instantiated in the
-    application main:
-
-    \snippet bars/graphmodifier.cpp 0
-
-    Let's take a closer look at parts of the code.
-
-    First we're creating the axes and the series into member variables to support changing them
-    easily later on, if we want to:
-
-    \snippet bars/graphmodifier.cpp 1
-
-    Then we're setting some of the visual qualities for the graph:
-
-    \snippet bars/graphmodifier.cpp 2
-
-    We're also setting up the axes and setting them to the graph as active axes:
-
-    \snippet bars/graphmodifier.cpp 3
-
-    We give axis labels a small autorotation angle to make them orient somewhat toward the
-    camera. This is done to improve axis label readability at extreme camera angles.
-
-    Next we initialize the visual properties of the series.
-    Note that the second series is initially not visible:
-
-    \snippet bars/graphmodifier.cpp 8
-
-    The series need to be added to the graph to show them:
-
-    \snippet bars/graphmodifier.cpp 4
-
-    Finally, we set the camera angle by calling the same method the camera angle change button
-    in the UI uses to cycle through various camera angles:
-
-    \snippet bars/graphmodifier.cpp 6
-
-    There you can see that the camera is controlled via the scene object of the graph:
-
-    \snippet bars/graphmodifier.cpp 10
-
-    For more information about using scene and cameras, see Q3DScene and Q3DCamera.
-
-    That concludes setting up the graph.
-
-    \section1 Adding Data to the Graph
-
-    At the end of the constructor there's a call:
-
-    \snippet bars/graphmodifier.cpp 9
-
-    This method is used to add data to the proxies of the two series:
-
-    \snippet bars/graphmodifier.cpp 5
-
-    Now the series have data to show.
-
-    \section1 Using Widgets to Control the Graph
-
-    There isn't much interaction yet, so let's continue by adding some widgets back in the
-    application main. Let's just focus on two as an example:
-
-    \snippet bars/main.cpp 4
-
-    We can use these slider widgets to rotate the graph instead of just using the mouse or
-    touch.
-
-    Let's add them to the vertical layout we created earlier:
-
-    \snippet bars/main.cpp 5
-
-    Then we'll connect them to methods in \c GraphModifier:
-
-    \snippet bars/main.cpp 6
-
-    Here are the methods in \c GraphModifier the signals were connected to. The camera
-    is controlled via the scene object. This time we specify the actual camera position
-    along the orbit around the center point, instead of specifying a preset camera angle:
-
-    \snippet bars/graphmodifier.cpp 7
-
-    Now these two sliders can be used to rotate the graph.
-
-    And so we have an application in which we can control:
-
-    \list
-        \li Graph rotation
-        \li Label style
-        \li Camera preset
-        \li Background visibility
-        \li Grid visibility
-        \li Bar shading smoothness
-        \li Visibility of the second bar series
-        \li Value axis direction
-        \li Axis title visibility and rotation
-        \li Data range to be shown
-        \li Bar style
-        \li Selection mode
-        \li Theme
-        \li Shadow quality
-        \li Font
-        \li Font size
-        \li Axis label rotation
-    \endlist
-
-    \section1 Selecting a Row/column by Clicking an Axis Label
-
-    Selection by axis label is default functionality for bar graphs. As an example, you can select
-    rows by clicking an axis label in the following way:
-
-    \list
-        \li Change selection mode to \c SelectionRow
-        \li Click a year label
-        \li The row with the clicked year is selected
-    \endlist
-
-    You can use the same method with \c SelectionSlice and \c SelectionItem flags, as long as
-    you have either \c SelectionRow or \c SelectionColumn set as well.
-
-    \section1 Zooming to Selection
-
-    As an example of adjusting camera target we have implemented an animation of zooming to
-    selection via a button press. Animation initializations are done in the constructor:
-
-    \snippet bars/graphmodifier.cpp 12
-
-    The function \c{GraphModifier::zoomToSelectedBar()} contains the rest of the functionality:
-
-    \snippet bars/graphmodifier.cpp 11
-
-    The QPropertyAnimation \c m_animationCameraTarget targets Q3DCamera::target property,
-    which takes a value normalized to the range (-1, 1). We figure out where the selected bar
-    is relative to axes, and use that as the end value for \c{m_animationCameraTarget}:
-
-    \snippet bars/graphmodifier.cpp 13
-    \dots
-    \snippet bars/graphmodifier.cpp 14
-
-    Likewise, we want to angle the camera so that it always points approximately to the center of
-    the graph at the end of the animation:
-
-    \snippet bars/graphmodifier.cpp 15
-
