详细描述

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]
        }
    }
}

特性文档编制

axisX : AbstractAxis

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

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

另请参阅 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.

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

另请参阅 axisX .

axisYSmoothing : real

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

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 . 取向

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 。默认值为 Qt.Vertical .

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.

另请参阅 BarSeries , LineSeries ，和 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.

方法文档编制

addSeries ( AbstractSeries series )

Appends a series into GraphsView 。若 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 )

返回 true 若 series is in the graph.

insertSeries ( int index , AbstractSeries series )

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

removeSeries ( AbstractSeries series )

移除 series from the graph.

removeSeries ( int index )

Removes the series specified by index from the graph.
