/*!
* \qmlproperty Graphs3D.OptimizationHint GraphsItem3D::optimizationHint
*
* \brief Specifies whether the default or legacy mode is used for rendering optimization.
*
* The default mode uses instanced rendering, and provides the full feature set
* at the best level of performance on most systems. The static mode optimizes
* graph rendering and is ideal for large non-changing data sets. It is slower
* with dynamic data changes and item rotations. Selection is not optimized, so
* using the static mode with massive data sets is not advisable. Legacy mode
* renders all items in th graph individually, without instancing. It should be
* used only if default mode does not work, that is the same as if the target
* system does not support instancing. Defaults to
* \l{QtGraphs3D::OptimizationHint::Default}{Default}.
*
* \note On some environments, large graphs using static optimization may not
* render, because all of the items are rendered using a single draw call, and
* different graphics drivers support different maximum vertice counts per call.
* This is mostly an issue on 32bit and OpenGL ES2 platforms. To work around
* this issue, choose an item mesh with a low vertex count or use the point mesh.

*
* This read-only property contains the latest graph position values along each

* range \c{[-1, 1]}. If the queried position was outside the graph bounds, the
* values will not reflect the real position, but will instead be some undefined
* position outside the range \c{[-1, 1]}. The value will be undefined until a
* query is made.
*
* There is no single correct 3D coordinate to match a particular screen
* position, so to be consistent, the queries are always done against the inner
* sides of an invisible box surrounding the graph.
*
* \note Bar graphs only allow querying graph position at the graph floor level,
* so the y-value is always zero for bar graphs and valid queries can be only
* made at screen positions that contain the floor of the graph.

*/
/*!
* \qmlproperty real GraphsItem3D::margin
*
* The absolute value used for the space left between the edge of the
* plottable graph area and the edge of the graph background.
*
* If the margin value is negative, the margins are determined automatically and
* can vary according to the size of the items in the series and the type of the
* graph. The value is interpreted as a fraction of the y-axis range if the
* graph aspect ratios have not been changed from the default values.
* Defaults to \c{-1.0}.
*
* \note Setting a smaller margin for a scatter graph than the automatically
* determined margin can cause the scatter items at the edges of the graph to
* overlap with the graph background.
*
* \note On scatter and surface graphs, if the margin is small in comparison to
* the axis label size, the positions of the edge labels of the axes are
* adjusted to avoid overlap with the edge labels of the neighboring axes.
