<Chart>.Scatter3DProjection (Function)

In french: <Graphe>.Nuage3DProjection

Indicates whether the points found in a series of a 3D Scatter chart must be be projected on a given plane. In this case, a straight line will link the point to its projection on the corresponding plan.

Example

// Projects in dots the points of series 1 on XY plane
CHART_My3DScatter.Scatter3DProjection(1, grPlaneXY, LineDotted)

// Initialize the Combo Box control
// Fills the list of line types
ListAdd(MySelf, "No line" + gStoredValue(LineNone))
ListAdd(MySelf, "Solid line" + gStoredValue(LineSolid))
ListAdd(MySelf, "Dashed line" + gStoredValue(LineDash))
ListAdd(MySelf, "Dotted line" + gStoredValue(LineDotted))
ListAdd(MySelf, "Dot-and-dash line" + gStoredValue(LineDotAndDash))

// By default, a dot-and-dash line is applied to this plane
MySelf = LineDotAndDash

// -----------------------------------------------------
// Code for selecting a row in the Combo Box control

// Applies the type of projection for the XY plane
CHART_Chart.Scatter3DProjection(1, grPlaneXY, MySelf)
CHART_Chart.Draw()

Syntax

<Chart control>.Scatter3DProjection(<Series number> , <Projection plane> [, <Type of line>])

<Chart control>: Control name

Name of the Chart control to use (in the window editor).

<Series number>: Integer

Number of the series to use.

<Projection plane>: Integer constant

Plane onto which the points will be projected:
grPlaneXY XY plane.
grPlaneXZ XZ plane.
grPlaneYZ YZ plane.

<Type of line>: Optional Integer constant

Type of line used to see the projection:
LineDash Line with dashes (------).
LineDotAndDash Line mixing dots and dashes (.-.-.-).
LineDotted Dotted line (........).
LineNone No line is drawn.
LineSolid
(Default value) Solid line.

Remarks

Configuring the display of projections

The projections are visible by default. The display of projections can be configured with <Chart>.Parameter.

You can:

hide the projections.

CHART_My3DScatter.Parameter(grProjectionScatter3D, grProjectionNone)

always display the projections.

CHART_MyScatter3D.Parameter(grProjectionScatter3D, grProjectionAlwaysVisible)

display the projections during the click on the point.

CHART_My3DScatter.Parameter(grProjectionScatter3D,grProjectionClick)
