配置Echarts大全

由于项目中需要用到Echarts，最近研究了一个星期。网上的教程也挺多的。磕磕碰碰的，难找到合适的例子。都说的马马虎虎。不废话了。开始吧。

这种上下排列的。。。

还有这种地图的。（如下）

还有就是配置的问题。（从echarts官网看例子。但是不能直接打开。如何在本地打开。）

我研究了一套非常好的配置方案。如下。

1.准备一个盒子，<div id="main1" style="width: 1600px;height:400px;"></div>

2.引入js 。 <script src="http://echarts.baidu.com/build/dist/echarts.js"></script>

3 .

// 路径配置开始
require.config({
　　paths: {
　　　　echarts: 'http://echarts.baidu.com/build/dist'
　　}
});

// 路径配置结束

// 使用柱状图就加载bar模块，按需加载
require(
　　　　　　[
　　　　　　　　'echarts',
　　　　　　　　'echarts/chart/bar',
　　　　　　　　'echarts/chart/line'
　　　　　　],
　　　　　　drawEcharts
);

// 函数调用
function drawEcharts(ec){
drawBar(ec);
drawBar2(ec);
drawBar3(ec);
drawBar4(ec);
　你在一个页面中，弄了几个echarts图表。你就弄几个函数。　
}

5. 具体的函数。

函数一： function drawBar(ec){

var myBarChart = ec.init(document.getElementById('main1'));

var option = {}

myBarChart.setOption(option,true);

}

函数二：。。。。。。。。。。。。可以写n个。记得调用。然后html里弄n个盒子。一个盒子对应一个函数。这就是整体怎么使用的。

难点二。怎么给柱子添加点击跳转。下面是公司给的设计稿。

点击柱子。跳转到指定页面。

在你做的drawBar函数内部。加上如下代码

var ecConfig = require('echarts/config');
function eConsole(param) {
switch (param.dataIndex) {
case 0: //柱子1
window.location.href = "stSubject.html";
break;
case 1: //柱子2
window.location.href = "stSubject.html";
break;
case 2: //柱子3
window.location.href = "stSubject.html";
break;
case 3: //柱子3
window.location.href = "stSubject.html";
break;
case 4: //柱子3
window.location.href = "stSubject.html";
break;
case 5: //柱子3
window.location.href = "stSubject.html";
break;

default:
break;
}
}
myBarChart.on(ecConfig.EVENT.CLICK, eConsole);

就实现了跳转。

完整代码如下。复制到本地，既可看到效果。（b不需要你下载任何js库）

                }
            ],
             yAxis : [

  /* 给柱状图绑定click事件 */
    var ecConfig = require('echarts/config');
    function eConsole(param) {
        switch (param.dataIndex) {
            case 0:    //柱子1
                window.location.href = "https://www.baidu.com/";
                break;
            case 1:  //柱子2
                window.location.href = "https://www.baidu.com/";
                break;
            case 2:  //柱子3
                window.location.href = "https://www.baidu.com/";
                break;
            case 3:  //柱子3
                window.location.href = "https://www.baidu.com/";
                break;
            case 4:  //柱子3
                window.location.href = "https://www.baidu.com/";
                break;
            case 5:  //柱子3
                window.location.href = "https://www.baidu.com/";
                break;

            default:
                break;
        }
    }
    myBarChart.on(ecConfig.EVENT.CLICK, eConsole);
      /* 给柱状图绑定click事件 */
}
</script>

这样。就能实现跳转啦。

难点二。如何把官网的例子在本地运行。

1 准备盒子。<div id="main" style="width: 1200px;height:800px;"></div>

2 引入这两个js 。。china.js是地图。务必引入。

2.5 或者可以引入china.json

这个需要配置如下代码：

//引入json地图
// $.get('json/china.json', function (chinaJson) {
// echarts.registerMap('china', chinaJson);
// });

3步：var myChart = echarts.init(document.getElementById('main'));

4部。就是把下载过来的代码粘贴到js中

官网的数据一般是这样的：

 var data = []
var geoCoordMap =[]

var convertedData = [
convertData(data),
convertData(data.sort(function(a, b) {
return b.value - a.value;
}).slice(0, 6))
];
data.sort(function(a, b) {
return a.value - b.value;
})

data: data
}]
};

function renderBrushed(params) {
var mainSeries = params.batch[0].selected[0];

var selectedItems = [];
var categoryData = [];
var barData = [];
var maxBar = 30;
var sum = 0;
var count = 0;

for (var i = 0; i < mainSeries.dataIndex.length; i++) {
var rawIndex = mainSeries.dataIndex[i];
var dataItem = convertedData[0][rawIndex];
var pmValue = dataItem.value[2];

sum += pmValue;
count++;

selectedItems.push(dataItem);
}

selectedItems.sort(function(a, b) {
// return b.value[2] - a.value[2];
return a.value - b.value;
});

for (var i = 0; i < Math.min(selectedItems.length, maxBar); i++) {
categoryData.push(selectedItems[i].name);
barData.push(selectedItems[i].value[2]);
}

this.setOption({
yAxis: {
data: categoryData
},
xAxis: {
axisLabel: {
show: !!count
}
},
title: {
id: 'statistic',
text: count ? '平均: ' + (sum / count).toFixed(4) : ''
},
series: {
id: 'bar',
// sort:'descending',
data: barData
}
});
}

最后。

myChart.setOption(option)
