Description

Scatter3D changing "selectionMode" has no effect.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  id: root
  width: 1280
  height: 960
  visible: true
  title: qsTr("Graphs 3D - Scatter Graph")

  Scatter3D {
    id: scatterGraph
    anchors.fill: parent

    selectionMode: Graphs3D.SelectionFlag.ItemRowAndColumn

    Scatter3DSeries {
      id: scatterSeries

      ItemModelScatterDataProxy {
        itemModel: dataModel
        xPosRole: "xPos"
        yPosRole: "yPos"
        zPosRole: "zPos"
      }
    }
  }

  ListModel {
    id: dataModel

    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 0; j <= 10; ++j) {
          dataModel.append({"xPos": i, "yPos": i + j, "zPos": j})
        }
      }
    }
  }
}

Setting Scatter3DSeries "visible" property to false does not hide the series. It does, however, influence the automatic min and max range of the axes.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  id: root
  width: 1280
  height: 960
  visible: true
  title: qsTr("Graphs 3D - Scatter Graph")

  Scatter3D {
    id: scatterGraph
    anchors.fill: parent

    Scatter3DSeries {
      id: scatterSeries

      visible: false

      ItemModelScatterDataProxy {
        itemModel: dataModel
        xPosRole: "xPos"
        yPosRole: "yPos"
        zPosRole: "zPos"
      }
    }
  }

  ListModel {
    id: dataModel
    ListElement{ xPos: "-0.5"; yPos: "-0.5"; zPos: "-0.5"; }
    ListElement{ xPos: "0.5"; yPos: "0.5"; zPos: "0.5"; }
  }
}

"labelAutoAngle" continuous label angle adjustment when rotating graph does not work - it changes the angle, however, when either the graph is rotated so that the graph background shifts or element selection is made. The same behaviour is observed with the titles.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  id: root
  width: 1280
  height: 960
  visible: true
  title: qsTr("Graphs 3D - Scatter Graph")

  Scatter3D {
    id: scatterGraph
    anchors.fill: parent

    axisX: Value3DAxis {
      labelAutoAngle: 90
    }

    axisY: Value3DAxis {
      labelAutoAngle: 90
    }

    axisZ: Value3DAxis {
      labelAutoAngle: 90
    }

    Scatter3DSeries {
      id: scatterSeries

      ItemModelScatterDataProxy {
        itemModel: dataModel
        xPosRole: "xPos"
        yPosRole: "yPos"
        zPosRole: "zPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = -10; i <= 10; ++i) {
        for (let j = -10; j <= 10; ++j) {
          dataModel.append({"xPos": i, "yPos": (i + j), "zPos": j})
        }
      }
    }
  }
}

"reversed" property in Value3DAxis used as axisX, axisY and axisZ in Scatter3D graph has no effect.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  id: root
  width: 1280
  height: 960
  visible: true
  title: qsTr("Graphs 3D - Scatter Graph")

  Scatter3D {
    id: scatterGraph
    anchors.fill: parent

    axisX: Value3DAxis {
      reversed: true
    }

    axisY: Value3DAxis {
      reversed: true
    }

    axisZ: Value3DAxis {
      reversed: true
    }

    Scatter3DSeries {
      id: scatterSeries

      ItemModelScatterDataProxy {
        itemModel: dataModel
        xPosRole: "xPos"
        yPosRole: "yPos"
        zPosRole: "zPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = -10; i <= 10; ++i) {
        for (let j = -10; j <= 10; ++j) {
          dataModel.append({"xPos": i, "yPos": (i + j), "zPos": j})
        }
      }
    }
  }
}

Scatter3D element selection or deselection, either by click or calling clearSelection() method does not update "selectedElement" property. Also, "clearSelection" method call does not seem to clear the selection properly - either selection persists visually until camera is rotated or the floating label alone stays until camera rotation occurs.
Minimal reproducible example:

import QtQuick
import QtQuick.Controls
import QtGraphs

Window {
  id: root
  width: 1280
  height: 960
  visible: true
  title: qsTr("Graphs 3D - Scatter Graph")

  Scatter3D {
    id: scatterGraph
    anchors.fill: parent

    onSelectedElementChanged: {
      console.log("Selected element changed")
    }

    Scatter3DSeries {
      id: scatterSeries
      singleHighlightColor: "red"

      ItemModelScatterDataProxy {
        itemModel: dataModel
        xPosRole: "xPos"
        yPosRole: "yPos"
        zPosRole: "zPos"
      }
    }
  }

  Button {
    anchors {
      top: scatterGraph.top
      horizontalCenter: parent.horizontalCenter
    }
    text: "Clear selection"
    onClicked: {
      scatterGraph.clearSelection()
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i < 10; ++i) {
        for (let j = 0; j < 10; ++j) {
          dataModel.append({"xPos": i, "yPos": i + j, "zPos": j})
        }
      }
    }
  }
}
