Class Chart3D

Chart for visualizing data in a 3-dimensional scene, with camera and light source(s).

Camera can be moved around with user interactions (mouse & touch). It is always oriented to face the center of the scene.

Light source is always located at the location of the Camera, and directed towards the center of Axes.

Data can be added to the Chart via various Series types, each with their own method of visualization:

 const pointLineSeries3D = chart3D.addPointLineSeries()
     .add( [
         { x: 0, y: 0, z: 0 },
         { x: 1, y: 0, z: 0 },
         { x: 2, y: 1, z: 0 }
     ] )

Methods

addBoxSeries

  • Create Series for visualization of large sets of individually configurable 3D Boxes.

    Example usage:

     // Construct a grid of vertical boxes.
     const data = [
         { x: 0, z: 0 },
         { x: 1, z: 0 },
         { x: 0, z: 1 },
         { x: 1, z: 1 }
     ]
         // Map coords into **BoxData**.
         .map( coords => {
         const height = Math.random() * 100
         return {
             xCenter: coords.x,
             yCenter: height / 2,
             zCenter: coords.z,
             xSize: 1,
             ySize: height,
             zSize: 1
         }
     })
     const chart = lightningChart().Chart3D()
     const boxSeries = chart.addBoxSeries()
         .invalidateData( data )
    

    Returns BoxSeries3D

    BoxSeries3D.

addLegendBox

  • Add a legendbox.

    Legendbox is a type of UI element, that floats inside the chart/component it is created inside. It can be freely moved around with user interactions, as well as positioned in application code.

    The purpose of legendbox is to describe the series and other visual components of the chart, by displaying their names and colors. Hovering over a series' legendbox entry will highlight that series, and clicking on the entry will toggle that series' visibility.

    Legendbox alignment:

    Alignment of legendbox can be selected by supplying one of the available LegendBoxBuilders to addLegendBox:

     // Default (vertical) LegendBox.
     const legendBox = ChartXY.addLegendBox()
    
     // Horizontal LegendBox.
     const horizontalLegendBox = ChartXY.addLegendBox(LegendBoxBuilders.HorizontalLegendBox)
    

    Custom Legendbox positioning:

    By default LegendBoxes are placed on the right side, or bottom of the chart (depending on alignment).

    A custom location can be configured with UIElement API:

    Position coordinate system is specified when creating legendbox.

    1. LegendBox with default positioning coordinate system.
     addLegendBox( LegendBoxBuilders.VerticalLegendBox )
         // Position = [0, 100] as percentages.
         .setPosition({ x: 50, y: 50 })
    
    1. Position in pixel coordinate system.
     addLegendBox( LegendBoxBuilders.VerticalLegendBox, chart.pixelScale )
         // Position = pixels.
         .setPosition({ x: 300, y: 100 })
    
    1. Position on Axes.
     addLegendBox( LegendBoxBuilders.VerticalLegendBox, { x: chartXY.getDefaultAxisX(), y: chartXY.getDefaultAxisY() } )
         // Position = Axis values.
         .setPosition({ x: 5, y: 5 })
    

    Parameters

    • builder: UILegendBoxBuilder

      LegendBoxBuilder. If omitted, VerticalLegendBox will be selected. Use LegendBoxBuilders for selection.

    • scale: UserScaleDefinition

      Optional parameter for altering the coordinate system used for positioning the LegendBox. Defaults to whole Chart in percentages [0, 100].

    Returns LegendBox & UIElement

    Object with two interfaces: LegendBox and UIElement.

addLineSeries

  • Method for adding a new LineSeries3D to the chart. This 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.

    To learn more about its features and usage, refer to LineSeries3D.

    Returns LineSeries3D

    New series.

addPointLineSeries

  • Method for adding a new PointLineSeries3D to the chart. This Series type for visualizing a collection of { x, y, z } coordinates by a continuous line stroke and markers.

    PointLineSeries3D 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.

    To learn more about its features and usage, refer to PointLineSeries3D.

    Returns PointLineSeries3D

    New series.

addPointSeries

  • Method for adding a new PointSeries3D to the chart. This series type for visualizing a collection of { x, y, z } coordinates by different markers.

    PointSeries3D 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.

    To learn more about its features and usage, refer to PointSeries3D.

    Readonly configuration:

    Some properties of PointSeries3D can only be configured when it is created. These arguments are all optional, and are wrapped in a single object parameter:

     // Example,
     const pointCloudSeries3D = Chart3D.addPointSeries({
         // Specify point series type as point cloud.
         type: PointSeriesTypes3D.Pixelated
     })
    

    To learn about available properties, refer to PointSeriesOptions3D.

    Type parameters

    Parameters

    • options: PointSeriesOptions3D<T>

      Optional object with readonly configuration arguments for PointSeries3D.

    Returns InstanceType<T>

    New series.

addSurfaceGridSeries

  • Add a Series for visualizing a Surface Grid with a static column and grid count. Has API for fast modification of cell Y and Intensity values.

    The grid is defined by imagining a plane along X and Z axis, split to < COLUMNS > (cells along X axis) and < ROWS > (cells along Z axis)

    The total amount of < CELLS > in a surface grid is calculated as columns * rows. Each < CELL > can be associated with DATA from an user data set.

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

    • A static data set in tens of millions range is rendered in a matter of seconds.
    • A data set in tens of millions range can be updated in less than a second.
    • Maximum data set size is entirely limited by available memory (RAM). Even billion (1 000 000 000) data points have been visualized on a personal computer. Interacting with massive surface charts (more than tens of millions data points) requires a powerful GPU !

    To learn more about its features and usage, refer to NewSurfaceGridSeries3D.

    Readonly configuration:

    Some properties of NewSurfaceGridSeries3D can only be configured when it is created. Some of these arguments are optional, while some are required. They are all wrapped in a single object parameter:

     // Example,
     const surfaceGridSeries = Chart3D.addSurfaceGridSeries({
         columns: 100,
         rows: 200,
     })
    

    To learn about these properties, refer to NewSurfaceGridSeries3DOptions.

    For scrolling surface grid, see addSurfaceScrollingGridSeries.

    Parameters

    Returns NewSurfaceGridSeries3D

    Surface Grid Series.

addSurfaceMeshSeries

  • Create Series for visualization of data by Surface Mesh.

    To learn more of capabilities and usage, see SurfaceMeshSeries3D

    Parameters

    • options: SurfaceOptions3D

      Optional object for passing readonly parameters to configure the created Series.

    Returns SurfaceMeshSeries3D

    SurfaceMeshSeries3D

addSurfaceScrollingGridSeries

  • Add a Series for visualizing a Surface Grid with API for pushing data in a scrolling manner (append new data on top of existing data).

    The grid is defined by imagining a plane along X and Z axis, split to < COLUMNS > (cells along X axis) and < ROWS > (cells along Z axis)

    The total amount of < CELLS > in a surface grid is calculated as columns * rows. Each < CELL > can be associated with DATA from an user data set.

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

    • A data set of tens of millions data points is rendered in a matter of seconds.
    • Maximum data set size is entirely limited by available memory (RAM). Even billion (1 000 000 000) data points have been visualized on a personal computer. Interacting with massive surface charts (more than tens of millions data points) requires a powerful GPU !
    • Scrolling Surface Grid input stream rate is virtually unlimited - even 10 million incoming data points per second can easily be processed. Application limitations usually come from previously mentioned RAM and/or GPU bottlenecks.

    To learn more about its features and usage, refer to SurfaceScrollingGridSeries3D.

    Readonly configuration:

    Some properties of SurfaceScrollingGridSeries3D can only be configured when it is created. Some of these arguments are optional, while some are required. They are all wrapped in a single object parameter:

     // Example,
     const surfaceScrollingGridSeries = Chart3D.addSurfaceScrollingGridSeries({
         columns: 100,
         rows: 200,
     })

    For static surface grid, see addSurfaceGridSeries.

    Parameters

    Returns SurfaceScrollingGridSeries3D

    Surface Scrolling Grid Series.

addSurfaceSeries

  • Create Series for visualization of data by surfaces.

    Example usage:

    • By default, creates SurfaceGridSeries3D

      const gridSurface3D = Chart3D.addSurfaceSeries()
      
    • By specifying options object with type-property, the returned Series' class can be selected

      const meshSurface3D = Chart3D.addSurfaceSeries({
         type: SurfaceSeriesTypes3D.Mesh
      })
      
    • The easiest way to define Surface geometry is to invalidate it via a callback function

      const resolution = 20
      const grid = chart3D.addSurfaceSeries( {
        type: SurfaceSeriesTypes3D.Grid,
        rows: resolution,
        columns: resolution,
        start: { x: 0, z: 0 },
        end: { x: 100, z: 100 },
        pixelate: true
      } )
        .invalidateYOnly( ( row, column, prev ) => {
            return Math.sin( row * 2 * Math.PI / resolution )
        } )
        .setFillStyle( new PalettedFill( {
             // Refer to "palette" examples for LUT creation.
             lut,
             lookUpProperty: 'y'
         } ) )

saveToFile

  • saveToFile(fileName: string, type?: undefined | string, encoderOptions?: undefined | number): this
  • Capture rendered state in an image file. Prompts the browser to download the created file.

    NOTE: The download might be blocked by browser/plugins as harmful. To prevent this, only call the method in events tied to user-interactions. From mouse-event handlers, for example.

    Has two optional parameters which directly reference JavaScript API HTMLCanvasElement.toDataURL. For supported image formats, compression quality, Etc. refer to:

    https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toDataURL

    Example usage:

    // Download 'screenshot.png'
    Panel.saveToFile('screenshot')
    // Attempt download 'maybeNotSupported.bmp'
    Panel.saveToFile('maybeNotSupported', 'image/bmp')
    // Attempt download jpeg.file with specified compression quality
    Panel.saveToFile('fileName', 'image/jpeg', 0.50)
    
    sideeffect

    If 'type' is not supported by browser, an Error will be thrown.

    Parameters

    • fileName: string

      Name of prompted download file as string. File extension shouldn't be included as it is automatically detected from 'type'-argument.

    • type: undefined | string

      A DOMString indicating the image format. The default format type is image/png.

    • encoderOptions: undefined | number

      A Number between 0 and 1 indicating the image quality to use for image formats that use lossy compression such as image/jpeg and image/webp. If this argument is anything else, the default value for image quality is used. The default value is 0.92.

Readonly axes

axes : object

3D Coordinate system selector to use with translatePoint3D function, which lets users translate coordinates between different 3D coordinate systems.

 // Example, translate coordinate from Chart3D Axes to World Space.
 const coordWorld = translatePoint3D(
     // Coordinate on Axes.
     { x: 10, y: 5, z: 25 },
     // Source coordinate system.
     chart3D.axes,
     // Target coordinate system.
     chart3D.world
 )

The axes selector describes the coordinate system of 3D charts Axes (X, Y, Z).

About 3D coordinate systems:

Chart3D camera location is configured in World Space, which is currently the primary reason for interacting with different 3D coordinate systems.

For example, depth sorting of transparent objects by rendering data based on their distance to the camera.

Depth sorting is required for blending stacked transparent objects.
