Class LineSeries3D

Series type for visualizing a collection of { x, y, z } coordinates by a continuous line stroke.

LineSeries3D is optimized for massive amounts of data - here are some reference specs to give an idea:

  • A static data set in millions data points range is rendered in hundreds of milliseconds (~200ms). Afterwards chart can be rotated and zoomed with 60 FPS.
  • With streaming data, even millions of data points can be streamed in every second, while retaining an interactive document.

Creating LineSeries3D:

LineSeries3D are created with Chart3D.addLineSeries method.

 // Example syntax, create line series 3D
 const lineSeries3D = Chart3D.addLineSeries()

Frequently used methods:

  • Append data points to series | add
  • Remove all data points from series | clear
  • Configure style of line stroke | setStrokeStyle
  • Remove series temporarily, or permanently | dispose
  • Restore series after dispose | restore

Color shading style.

By default, LineSeries3D uses Phong shading style.

This can be changed with LineSeries3D.setColorShadingStyle(new ColorShadingStyles.Simple())

Related information:

To combine line stroke with markers over each data coordinate, PointLineSeries3D can be used.

    Returns this

    Object itself for fluent interface.

setDepthTestEnabled

  • setDepthTestEnabled(enabled: boolean): this
  • Set 3D depth test enabled for this series.

    By default this is enabled, meaning that any series that is rendered after this series and is behind this series will not be rendered.

    Can be disabled to alter 3D rendering behavior.

     // Example syntax, disable depth test.
     pointSeries3D.setDepthTestEnabled(false)

      Depth test enabled?

    Returns this

    Object itself for fluent interface.

setHighlightOnHover

  • setHighlightOnHover(state: boolean): this
  • Set highlight on mouse hover enabled or disabled.

    Mouse interactions have to be enabled on the component for this to function as expected. See setMouseInteractions for more information.

    Parameters

    • state: boolean

      True if highlighting on mouse hover, false if no highlight on mouse hover

    Returns this

    Object itself for fluent interface.

setHighlighted

  • setHighlighted(highLight: boolean): this
  • Enable or disable forced highlighting of component

    Parameters

    • highLight: boolean

      True for enabled and false for disabled

    Returns this

    component itself for fluent interface

setLineStyle

  • Set line style of Series.

    Example usage:

    • Construct new SolidLine object
      lineSeries3D.setStrokeStyle( new SolidLine({
         thickness: 5,
         fillStyle: new SolidFill({ color: ColorHEX('#FFF') })
      }) )
      
    • Change thickness of existing SolidLine configuration
      lineSeries.setStrokeStyle( (solidLine) => solidLine
         .setThickness( 5 )
      )
      
    deprecated

    Will be removed in v.4.0. Use setStrokeStyle instead.

    Parameters

    Returns this

    Object itself for fluent interface

setLineStyleHighlight

  • Set line style of Series when it is highlighted.

    Example usage:

    • Construct new SolidLine object
      lineSeries3D.setStrokeStyle( new SolidLine({
         thickness: 5,
         fillStyle: new SolidFill({ color: ColorHEX('#FFF') })
      }) )
      
    • Change thickness of existing SolidLine configuration
      lineSeries.setStrokeStyle( (solidLine) => solidLine
         .setThickness( 5 )
      )
      
    • Assign highlight style automatically based on normal style
      lineSeries.setStrokeStyleHighlight( undefined )
      
    deprecated

    Will be removed in v.4.0. Use setStrokeStyleHighlight instead.

    Parameters

    Returns this

    Object itself for fluent interface.

setMouseInteractions

  • setMouseInteractions(state: boolean): this
  • Set component mouse interactions enabled or disabled.

    Disabling mouse interactions means that the objects below this component can be interacted through it.

    Possible side-effects from disabling mouse interactions:

    • Mouse events are not triggered. For example, onMouseMove.
    • Mouse driven highlighting will not work.

    Parameters

    • state: boolean

      Specifies state of mouse interactions

    Returns this

    Object itself for fluent interface

setName

  • setName(name: string): this
  • Sets the name of the Component updating attached LegendBox entries

    Parameters

    • name: string

      Name of the Component

    Returns this

    Object itself

setStrokeStyle

  • Set stroke style of Series.

     // Example syntax, specify LineStyle
     LineSeries3D.setStrokeStyle(new SolidLine({
         thickness: 2,
         fillStyle: new SolidFill({ color: ColorHEX('#F00') })
     }))
    
     // Example syntax, change active LineStyle
     LineSeries3D.setStrokeStyle((stroke) => stroke.setThickness(5))
    

    Use -1 thickness to enable primitive line rendering. Primitive line rendering can have slightly better rendering performance than line with 1 thickness but the quality of line is not as good.

     LineSeries3D.setStrokeStyle((solidLine) => solidLine.setThickness(-1))
    
    • Supported fill styles:

    SolidFill:

    Solid color for entire line series.

     // Example, solid colored line.
     LineSeries3D.setStrokeStyle(new SolidLine({
         thickness: 2,
         fillStyle: new SolidFill({ color: ColorRGBA(255, 0, 0) })
     }))
    

    To learn more about available Color factories, see ColorRGBA

    PalettedFill:

    Color line stroke dynamically based on x, y or z coordinate.

     // Example, dynamic color by Y coordinates
     LineSeries3D.setStrokeStyle(new SolidLine({
         thickness: 2,
         fillStyle: new PalettedFill({
             lookUpProperty: 'y',
             lut: new LUT({
                 interpolate: true,
                 steps: [
                     { value: 0, color: ColorRGBA(255, 0, 0) },
                     { value: 100, color: ColorRGBA(0, 255, 0) },
                 ]
             })
         })
     }))
    

    To learn more about Color lookup tables, see LUT.

    • Primitive 3D line rendering

    LineSeries3D has a special feature for drawing primitive line sets.

    When enabled, this will draw all line segments as exactly 1 pixel thick on the monitor (regardless of distance from camera).

    As a benefit, this is considerably lighter on the GPU, which is especially good with mobile and laptop devices with weak GPUs.

    Primitive drawing is enabled by setting stroke thickness to -1:

     // Enable primitive 3D line drawing.
     LineSeries3D.setStrokeStyle((stroke) => stroke.setThickness(-1))
    
    • Other information

    In 3D, line thickness is not configured exactly as pixels (since the size of pixel is not affected by distance from camera).

    However, for usage convenience, you can consider line thickness in 3D as pixels just the same as 2D, even if the resulting visualization will have some differences.

    Parameters

    Returns this

    Object itself for fluent interface.

setStrokeStyleHighlight

  • Set line style of Series when it is highlighted.

    Example usage:

    • Construct new SolidLine object
      lineSeries3D.setStrokeStyle( new SolidLine({
         thickness: 5,
         fillStyle: new SolidFill({ color: ColorHEX('#FFF') })
      }) )
      
    • Change thickness of existing SolidLine configuration
      lineSeries.setStrokeStyle( (solidLine) => solidLine
         .setThickness( 5 )
      )
      
    • Assign highlight style automatically based on normal style
      lineSeries.setStrokeStyleHighlight( undefined )
      

    Parameters

    Returns this

    Object itself for fluent interface.
