集成 extjs 和 highcharts

通常在商业项目上，尽量只选择一个库，以减少成本。但如果只是用于非盈利项目上，那么，可以把两者结合起来，既可以用到 extjs 强大的类管理，又可以用到 highcharts 强大的图像功能。各取两者的优势，也是一种不错的使用办法哦。

1 导入库

<link rel="stylesheet" type="text/css" href="../ext-4.1.1a/resources/css/ext-all.css">

<script type="text/javascript" src="../ext-4.1.1a/ext-debug.js"></script>

<script type="text/javascript" src="../jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="../Highcharts-4.0.4/js/highcharts.js"></script>

<script type="text/javascript" src="app.js"></script>

2 全局配

// extjs 的路径配置
Ext.Loader.setConfig({
    enabled: true,
    paths: {
        jack : 'app/jack'
    }
});


// highchart 的全局配置
Highcharts.setOptions({
    global: {
        useUTC: false
    },
    // colors: {
    // },
    // lang: {
    // },
    chart: {
        animation: false
    }
});

3 类定义

Ext.define('jack.view.TemperatureHC', {

    extend: 'Ext.panel.Panel',

    config: {
        panelTitle: null,

        chartTitle: null
    },

    requires: [
        'Ext.panel.Panel'
    ],

    
    highchart: null,

    constructor: function (config) {

        this.initConfig(config);

        this.callParent(arguments);
    },

    initComponent: function() {
        var me = this;

        if (me.panelTitle) {
            me.title = me.panelTitle;
        }

        this.callParent(arguments);
    },

    afterComponentLayout: function(width, height, oldWidth, oldHeight) {
        var me = this;

        var chartId = me.id + "-body";

        me.highchart = new Highcharts.Chart({
            chart: {
                renderTo: chartId,
                animation: false
            },
            title: {
                text: me.chartTitle
            },
            xAxis: {
                categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
            },
            yAxis: {
                title: {
                    text: 'Temperature (°C)'
                },
                plotLines: [{
                    value: 0,
                    width: 1,
                    color: '#808080'
                }]
            },
            tooltip: {
                valueSuffix: '°C'
            },
            legend: {
                layout: 'vertical',
                align: 'right',
                verticalAlign: 'middle',
                borderWidth: 0
            },
            series: [{
                name: 'Tokyo',
                data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
            }, {
                name: 'New York',
                data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
            }, {
                name: 'Berlin',
                data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
            }, {
                name: 'London',
                data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
            }]
        });
    }
});

4 包含及显示

Ext.require([
    'Ext.container.Container',
    'jack.view.TemperatureHC'
]);


var pageContainer = null;

Ext.onReady(function () {

    pageContainer = Ext.create('jack.view.TemperatureHC', {
        id: 'htContainer',
        width: 800,
        height: 300,
        panelTitle: '今年温度',
        renderTo: Ext.getBody()
    });

});
