## Detailed Description

This class collects the series and theming together and draws the graphs. You will need to import Qt Graphs module to use this type:

     import QtGraphs

After that you can use GraphsView in your qml files:

     import QtQuick
     import QtGraphs

     GraphsView {
         anchors.fill: parent
         theme: GraphsTheme {
             colorScheme: GraphsTheme.ColorScheme.Dark
             seriesColors: ["#E0D080", "#B0A060"]
             borderColors: ["#807040", "#706030"]
             grid.mainColor: "#ccccff"
             grid.subColor: "#eeeeff"
             axisY.mainColor: "#ccccff"
             axisY.subColor: "#eeeeff"
         }
         axisX: BarCategoryAxis {
             categories: ["2023", "2024", "2025"]
             lineVisible: false
         }
         axisY: ValueAxis {
             min: 0
             max: 10
             subTickCount: 4
         }
         BarSeries {
             BarSet {
                 values: [7, 6, 9]
             }
             BarSet {
                 values: [9, 8, 6]
             }
         }
     }

## Property Documentation

### axisX : AbstractAxis

The x-axis used for the series inside this view.

Note: Setting the same axis to multiple GraphsViews is not supported.

See also axisY.

### axisXSmoothing : real

Controls the graph X axis smoothing (antialiasing) amount. By default, the smoothing is `1.0`.

### axisY : AbstractAxis

The y-axis used for the series inside this view.

Note: Setting the same axis to multiple GraphsViews is not supported.

See also axisX.

### axisYSmoothing : real

Controls the graph Y axis smoothing (antialiasing) amount. By default, the smoothing is `1.0`.

### clipPlotArea : bool `[since 6.10]`

Controls whether graph items should be clipped if they go outside of a plot area. The default value is `true`.

This property was introduced in Qt 6.10.

See also plotArea.

### gridSmoothing : real

Controls the graph grid smoothing (antialiasing) amount. By default, the smoothing is `1.0`.

### marginBottom : real

The amount of empty space on the bottom of the graph. By default, the margin is 20.

### marginLeft : real

The amount of empty space on the left of the graph. By default, the margin is 20.

### marginRight : real

The amount of empty space on the right of the graph. By default, the margin is 20.

### marginTop : real

The amount of empty space on the top of the graph. By default, the margin is 20.

### orientation : Qt.Orientation

Determines the orientation of the GraphsView. When the orientation is Qt.Horizontal, axisX and axisY will switch the positions so that axisX is rendered vertically and axisY horizontally. This property is currently used by the BarSeries. The default value is Qt.Vertical.

### panStyle : enumeration

Determines the pan style of the GraphsView. Panning works by manipulating the pan property of a ValueAxis. The default value is `GraphsView.PanStyle.None`.

Constant | Description
--- | ---
`GraphsView.PanStyle.None` | Panning is disabled.
`GraphsView.PanStyle.Drag` | Mouse and touch drag pan the view around.

### plotArea : rect `[read-only, since 6.9]`

The rectangle within which the graph is drawn. This is the GraphsView area minus axis areas and margins.

This property was introduced in Qt 6.9.

See also marginTop, marginBottom, marginLeft, and marginRight.

### seriesList : list `[read-only]`

List of series that are rendered by the GraphsView. Filled automatically with the series type children of the GraphsView.

This is the default property, so child elements are automatically added into the series list.

See also BarSeries, LineSeries, and ScatterSeries.

### shadowBarWidth : real

Controls the graph grid shadow width. By default, shadow width is set to `2.0`.

### shadowColor : color

Controls the graph grid shadow color. By default, shadow color is set to `black`.

### shadowSmoothing : real

Controls the graph grid shadow smoothing (antialiasing) amount. By default, shadow smoothing is set to `4.0`.

### shadowVisible : bool

Controls if the graph grid shadow is visible. By default, shadow visibility is set to `false`.

### shadowXOffset : real

Controls the graph grid shadow X offset. By default, shadow X offset is set to `0.0`.

### shadowYOffset : real

Controls the graph grid shadow Y offset. By default, shadow Y offset is set to `0.0`.

### theme : GraphsTheme

The theme used by the graph. Determines coloring, axis lines, fonts etc. If theme has not been set, the default theme is used.

### zoomAreaDelegate : Component

Determines the QML element that is drawn when the user performs a drag motion to zoom in to an area.

### zoomAreaEnabled : bool

Zoom area changes mouse and touch dragging to draw a box determined by `zoomAreaDelegate`. Upon release the graph ValueAxis zoom and pan properties are changed so that the view covers only the area intersected by the drawn box.

See also zoomAreaDelegate.

### zoomSensitivity : real

Determines how fast zoom value changes while zooming.

### zoomStyle : enumeration

Determines the zoom style of the GraphsView. Zooming works by manipulating the ValueAxis zoom property. The default value is `GraphsView.ZoomStyle.None`.

Constant | Description
--- | ---
`GraphsView.ZoomStyle.None` | Zooming is disabled.
`GraphsView.ZoomStyle.Center` | Pinch zoom and mouse wheel zoom towards the center of the graph view.

## Method Documentation

### void addSeries(AbstractSeries series)

Appends a series into GraphsView. If the series is null, it will not be added. If the series already belongs to the graph, it will be moved into the end.

### bool hasSeries(AbstractSeries series)

Returns `true` if the series is in the graph.

### void insertSeries(int index, AbstractSeries series)

Inserts a series at the position specified by index. If the series is null, it will not be inserted. If the series already belongs to the graph, it will be moved into index.

### void removeSeries(AbstractSeries series)

Removes the series from the graph.

### void removeSeries(int index)

Removes the series specified by index from the graph.
