Qt Charts QML 類型

Qt Charts QML API 是在 QML 應用程序中，直觀且簡單展示圖錶的手段。

使用以下 QML 創建簡單餅狀圖錶：

import QtQuick 2.0
import QtCharts 2.0
ChartView {
    width: 400
    height: 300
    theme: ChartView.ChartThemeBrownSand
    antialiasing: true
    PieSeries {
        id: pieSeries
        PieSlice { label: "eaten"; value: 94.9 }
        PieSlice { label: "not yet eaten"; value: 5.1 }
    }
}

注意： 從 Qt Creator 3.0 起，采用基於 Qt Quick 2 模闆的 Qt Quick 應用程序嚮導創建的工程使用 QGuiApplication 在默認情況下。由於 Qt Charts 利用 Qt 圖形視圖框架為繪製， QApplication 必須使用。采用嚮導創建的工程可用於 Qt Charts 後於 QGuiApplication 被替換采用 QApplication .
