使用流程

BDP使用了HTTPS协议,不支持混用HTTP资源,所以引用的第三方库资源文件都需要放在支持HTTPS的服务器上,对于ECharts,你可使用如下链接

https://www.bdp.cn/pmresources/libs/echarts/3.6.0/echarts.all.min.js

在下方找到bdp-echarts-demo,将文件中的代码粘贴到自定义图表的代码编辑区中,将语言切换成javascript模式,然后将echarts官方demo的示例代码(如http://echarts.baidu.com/demo.html#geo-lines)贴到第19行处,点击运行即可预览效果 点击保存即可保存代码 如果需要更换其他demo代码,只需将第2步的示例代码删除,粘贴新的代码即可 注:部分echarts的官方demo中会加载一些外网的资源文件,如果发现示例代码中有一些外网的url,只需将这个url打开,把外网的资源下载下来,像第1步那样操作,将资源文件上传到内网服务器中,用内网的url替换到示例代码中即可 下方bdp-echarts-geoline,是一个echarts迁徙图的例子,可供参考,直接贴到自定义图表的代码编辑区即可使用

bdp-echarts-demo

var echartsUrl = "https://www.bdp.cn/pmresources/libs/echarts/3.6.0/echarts.all.min.js";
var option, myChart, app = {};
thirdPluginLoader({
 libSrc: echartsUrl,
   libId: window.echarts,

     console.log("init echarts done.")
     myChart = echarts.init(chart.$elem.get(0));
     echartsCode();       
     myChart.setOption(option);
   }
});
