Usage examples

Using a built-in theme without any modifications:

Scatter3D {
    ...
    theme: Theme3D { type: Theme3D.ThemeRetro }
    ...
}

Using a built-in theme and modifying some properties:

Bars3D {
    ...
    theme: Theme3D {
        type: Theme3D.ThemeRetro
        labelBorderEnabled: true
        font.pointSize: 35
        labelBackgroundEnabled: false
    }
    ...
}

Using a user-defined theme:

Surface3D {
    ...
    theme: Theme3D {
        ambientLightStrength: 0.5
        backgroundColor: "red"
        backgroundEnabled: true
        baseColor: "blue"
        colorStyle: Theme3D.ColorStyleUniform
        font.family: "Lucida Handwriting"
        font.pointSize: 35
        gridEnabled: false
        gridLineColor: "black"
        highlightLightStrength: 0.5
        labelBackgroundColor: "black"
        labelBackgroundEnabled: true
        labelBorderEnabled: false
        labelTextColor: "white"
        lightColor: "yellow"
        lightStrength: 0.4
        multiHighlightColor: "green"
        singleHighlightColor: "darkRed"
