DataCursor 3D

Starting from version 10.5, View3D has a built-in data cursor (similar to DataCursor in ViewXY), which automatically tracks the closest series value to the mouse cursor and shows it in a result table. The DataCursor consists of hair cross lines for all three axes, a tracking point at the location of the closest data value, indicators showing the current values on axis scales, and the result table, which besides the axis values also shows the series name and its color.

Data cursor can be enabled or disabled via Visible property. It is also possible to hide some of the cursor components such as the lines or the indicators labels for the axes individually by setting ShowHaircrossLines or ShowLabels, or other respective “Show” properties based on what should be hidden, false. IndicatorLength and IndicatorWidth modify the axis indicators, TrackingPointStyle allows altering the tracking point while LineStyle changes the hair cross lines. Results property contains all the options to modify the result table. The appearance of the axis labels can be modified under Configuration category.

// Enables data cursor but hides its axis indicator labels.
_chart.View3D.DataCursor.Visible = true;
_chart.View3D.DataCursor.ShowLabels = false;
// Modifying the result table.
_chart.View3D.DataCursor.ShowResultTable = true;
_chart.View3D.DataCursor.Results.Background.Color = Colors.DarkBlue;

Data cursor changes its behaviour depending on whether the tracked series has a visible line or just visible data points (scatter plot). If the line is visible, the cursor finds the nearest series and its value to the cursor’s current position. If there are no lines visible, the cursor tracks the nearest data point in any direction. Enabling SnapToNearestDataPoint overrides this making the cursor always finding the nearest actual data point value in any direction.

Data cursor works with every View3D series and object except for Rectangle3D and VolumeModels.
