Description

Same in datavis ItemModelSurfaceDataProxy "columnRolePattern" and "columnRoleReplace" (as well as their row equivalents) do not work.
Minimal reproducible example:

import QtQuick
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    Surface3DSeries {
      id: surfaceSeries

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        rowRole: "xPos"
        columnRole: "timestamp"
        columnRolePattern: /(?:\d{2}.){2}(\d{4})/ // Match date, capture only year
        columnRoleReplace: "\\1" // Present the captured year
        yPosRole: "yPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 2000; j <= 2015; ++j) {
          dataModel.append({"xPos": i, "yPos": i + j, "timestamp": "10.10." + j})
        }
      }
    }
  }
}

Fix: Clear picked status of models when clearing selection ~~"clearSelection" method does not drop selection, it only nullifies the floating label contents, leaving empty border.~~
~~Minimal reproducible example:~~

import QtQuick
import QtQuick.Controls
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    Surface3DSeries {
      id: surfaceSeries

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        columnRole: "xPos"
        yPosRole: "yPos"
        rowRole: "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})
        }
      }
    }
  }

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

Fixed in Qt 6.8.1 ~~Surface3DSeries "mesh" property does not influence the selection pointer shape.~~
~~Minimal reproducible example:~~

import QtQuick
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    Surface3DSeries {
      id: surfaceSeries

      mesh: Abstract3DSeries.Mesh.Pyramid

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        rowRole: "xPos"
        columnRole: "zPos"
        yPosRole: "yPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 20; j <= 30; ++j) {
          dataModel.append({"xPos": i, "yPos": i + j, "zPos": j})
        }
      }
    }
  }
}

"cameraTargetPosition" property does not work as described in the docs; values are not clamped, "x" coordinate 1.0 value does not translate to the edge of the X axis, "z" coordinate value does not translate to the edge of the Z axis but instead moves further from the graph as the value increases.
Minimal reproducible example:

import QtQuick
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    cameraTargetPosition: Qt.vector3d(1.0, 0, 5.0)

    Surface3DSeries {
      id: surfaceSeries

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        rowRole: "xPos"
        columnRole: "zPos"
        yPosRole: "yPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 20; j <= 30; ++j) {
          dataModel.append({"xPos": i, "yPos": i + j, "zPos": j})
        }
      }
    }
  }
}

This is a documented known issue (and there is a separate ticket for it) ** 3D surface graph does not seem to cast any shadow on the background despite "shadowStrength" property set to a significant value.
~~Minimal reproducible example:~~

import QtQuick
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    shadowStrength: 100

    Surface3DSeries {
      id: surfaceSeries

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        rowRole: "xPos"
        columnRole: "zPos"
        yPosRole: "yPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 20; j <= 30; ++j) {
          dataModel.append({"xPos": i, "yPos": i * j, "zPos": j})
        }
      }
    }
  }
}

Using LogValue3DAxisFormatter for Y axis crashes the application.
Minimal reproducible example:

import QtQuick
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    axisY: Value3DAxis {
      formatter: LogValue3DAxisFormatter {}
    }

    Surface3DSeries {
      id: surfaceSeries

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        rowRole: "xPos"
        columnRole: "zPos"
        yPosRole: "yPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 20; j <= 30; ++j) {
          dataModel.append({"xPos": i, "yPos": i * j, "zPos": j})
        }
      }
    }
  }
}

Fixed in Qt 6.8.2 ~~"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.~~
~~Minimal reproducible example:~~

import QtQuick
import QtGraphs

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

  Surface3D {
    id: surfaceGraph
    anchors.fill: parent

    axisX: Value3DAxis {
      labelAutoAngle: 90
    }

    axisY: Value3DAxis {
      labelAutoAngle: 90
    }

    axisZ: Value3DAxis {
      labelAutoAngle: 90
    }

    Surface3DSeries {
      id: surfaceSeries

      ItemModelSurfaceDataProxy {
        itemModel: dataModel
        rowRole: "xPos"
        columnRole: "zPos"
        yPosRole: "yPos"
      }
    }
  }

  ListModel {
    id: dataModel
    Component.onCompleted: {
      for (let i = 0; i <= 10; ++i) {
        for (let j = 20; j <= 30; ++j) {
          dataModel.append({"xPos": i, "yPos": i * j, "zPos": j})
        }
      }
    }
  }
}
