Axis 3D Ranging - AutoRange & VisibleRange
Axes in SciChart 3D shares the same SCIAxisCore base class with SciChart 2D Axes.
Many of the AxisCore features are shared.
For your convenience, some of the documentation has been duplicated here, with some referring to other sections of the user manual.
Axis 3D AutoRange
SCIAxisBase3D derived Types also have AutoRanging behaviour as per the 2D axis types.
The ISCIAxisCore.autoRange property defines how the axis will auto-range when data is changed.
There are 3 possible auto-range modes, which are listed below:
SCIAutoRange.SCIAutoRange_Once- axis will attempt to fit the data only when you start the chart.SCIAutoRange.SCIAutoRange_Always- axis will attempt to fit the data every time the chart is drawn .SCIAutoRange.SCIAutoRange_Never- axis will never auto-range.
In a 3D Axis, AutoRanging means, given a fixed size of Axis in 3D world coordinates, change the VisibleRange Max/Min to fit the data.
Dynamically positioning the Camera to view all of the 3D Chart is known as Zoom to Fit and is performed by -[ISCICameraController zoomToFit].
NOTE: The AutoRanging are shared between SciChart 2D and SciChart 3D. For a full walk-through, including code-samples, please see the Axis Ranging - AutoRange article.
Axis 3D VisibleRange
Every 3D Axis type can work with a specific range type that conforms to the ISCIRange protocol. It depends on the data type that the axis can work with. Please review the article on 3D Axis Types to learn more.
The ISCIAxisCore.visibleRange is an actual axis range, measured in chart units. This is a part of a chart that is currently visible in a viewport.
This property allows you to set or get the visibleRange on the axis.
NOTE: The VisibleRange APIs are shared between SciChart 2D and SciChart 3D. For a full walk-through of VisibleRange API, including code-samples, please see the following articles:
