Qt Charts for MCUs QML 类型

概述

The Qt Charts for MCUs module provides a set of easy to use charts components for Qt Quick Ultralite.

Qt Charts for MCUs aims to be compatible with Qt Charts. See Qt Charts Compatibility 了解细节。

注意： This module is a technology preview. Many features from Qt Charts are not yet available and there is no source-compatibility guarantee between versions.

快速入门

To use the Qt Charts for MCUs QML types, link your application to the Qul::QuickUltraliteCharts CMake target:

target_link_libraries(app Qul::QuickUltralite Qul::QuickUltraliteCharts Qul::QuickUltralitePlatform)
							

And add the following import statement to your .qml 文件：

import QtCharts 2.15
							

使用 ChartView QML type along with one of the series types, like BarSeries , to create a chart:

ChartView {
    title: "Test Chart"
    margins { left: 80; right: 50; bottom: 50; top: 50 }
    BarSeries {
        axisX: BarCategoryAxis {
            BarCategoryValue { value: "2016" }
            BarCategoryValue { value: "2017" }
            BarCategoryValue { value: "2018" }
        }
        BarSet {
            BarSetValue { value: 3 }
            BarSetValue { value: 5 }
            BarSetValue { value: 2 }
        }
        BarSet {
            BarSetValue { value: 1 }
            BarSetValue { value: 4 }
            BarSetValue { value: 3 }
        }
    }
