This article mainly introduces the introduction of echart. The editor thinks it is quite good. Now I will share it with you and give you a reference. Let’s follow the editor to take a look

1. Download the plug-in

The following is the download link for ECharts. It should be noted that ECharts also relies on Another plug-in is called ZRender. Of course, ZRender is not required for most charts, but ZRender is required for map controls and other complex rendering controls. In order to avoid unnecessary problems, it is recommended that you also download ZRender when downloading ECharts.

ECharts download address: http://echarts.baidu.com/

ZRender download address: http://ecomfe.github.io/zrender/index. html

After downloading, unzip the respective file directory structures as follows:

ECharts:

   

ZRender:


##2. Plug-in reference

First, create a new Web application, and then add the file you just downloaded. The specific directory structure is as follows:


Here are the following Points to note:

  • All files related to ECharts are in the echarts folder

  • The contents of the echarts folder are divided into two Part

1) One part is the js file starting with echarts. These files all come from the files in the js folder in the ECharts file directory in 1., that is, in 1. The files under js marked in the red box in the picture. As follows:

#2) The other part is a folder named zrender. What needs special attention here is that the folder must be named zrender, because in the js of echarts The references to zrender in the file all have zrender as the root directory. The content of the zrender folder is the content of the src folder in the zrender file directory in 1., as follows:


3. Specific use in the page

After configuring according to the above steps, we can reference it in the page. Here I mainly This is to demonstrate the use of the map control, because the reference of the map is different from the reference of other basic graphics. The presentation of other graphics will also be briefly demonstrated.

MapChart

First add an aspx page or html page in the same directory as the echarts folder in 2 (that is, the Modules folder). It should be noted that if you use echarts in an aspx page, you need to place the p to be rendered outside the form tag, otherwise the graphics will not be displayed.


Add a reference to echarts in the head tag as follows: 


<head runat="server"> 
  <title></title> 
  <script src="echarts/esl.js" type="text/javascript"></script> 
</head>

In the body tag, In addition to the form tag, add a p, which is used as a container for chart rendering. As follows: 



<body> 
 
<p id="main"style="height:500px;border:1px solid #ccc;padding:10px;"></p> 
 
…………… 
 
…………… 
 
</body>

Under the p tag added above, add the following js code snippet, as follows: 



 <script type="text/javascript"> 
 
    //为模块加载器配置echarts的路径，这里主要是配置map图表的路径，其他的图表跟map的配置还不太一样，下边也会做另一种类型的图表事例。 
这里引用的主要是echarts文件夹下的echarts-map文件，而其他类型的图表引用的都是echarts文件夹下的echarts文件。 
 
    require.config({

      } 
 
    }); 
 
   //动态加载echarts，在回掉函数中使用，要注意保持按需加载结构定义图表路径

       //以下的这段代码主要是用来处理用户的选择，应用场景是可以做地图的交互，比如点击地图上的某一个省，获取相应的省的指标变化等。 
       //需要特别注意的是，如果需要点击某一省作地图的操作交互的话，还需要为series属性的每一项添加一个selectedMode属性，这里的属性值为 &#39;single&#39;即单选，也可多选 
  varecConfig= require(&#39;echarts/config&#39;); 
      myChart.on(ecConfig.EVENT.MAP_SELECTED,function (param) { 
        varselected=param.selected;

        vardata= []; 
        varlegendData= []; 
        varname; 
        for (varp=0,len=mapSeries.data.length; p<len; p++) { 
          name=mapSeries.data[p].name; 
          mapSeries.data[p].selected=selected[name]; 
          if (selected[name]) { 
            alert(name); //这里只是简单的做一个事例说明，弹出用户所选的省，如需做其他的扩展，可以在这里边添加相应的操作  
 
          } 
        } 
      });         
      myChart.setOption(option); 
    } 
  ); 
  </script>

After completing the above operations, the effect is as shown below:


LineChart

Except for map charts, other icons are used in the same way. In fact, the difference between other charts and map charts is the reference to the configuration file. Here is only an example of a line chart, the other examples are the same.
