graph 加载数据，产生off未定义错误

[asdfhalkehflkajdhf]

1、数据和错误信息可以查看以下两个链接。
这两个数据是使用程序跑出来，并不存在格式不对的问题。因为有的是可以显示

错误显示

echarts.js:54307 Uncaught TypeError: Cannot read property 'off' of undefined at echarts.js:54307 at Graph.graphProto.eachEdge (echarts.js:52679) at ExtendedClass.render (echarts.js:54304) at Task.progress (echarts.js:24193) at doProgress (echarts.js:23115) at Task.taskProto.perform (echarts.js:23038) at echarts.js:27882 at ExtendedClass.<anonymous> (echarts.js:21073) at Array.forEach (<anonymous>) at each$1 (echarts.js:528)

正常显示

２、在graph中我使用这个双击是不管用
chartObj.on('dblclick', function (params) {
console.log(params);
});

我试过4.1的多个版本，目前使用的echars版本是echarts-4.2.0-rc.2，
尝试去解决问题，但太深入了。

These two data are running out of the program, and there is no problem of incorrect format. Because some can be displayed.

    2, in graph, I use this double click is useless.
    ChartObj.on ('dblclick', function (params) {
    Console.log (params);
    });
    I tried more than 4.1 versions, and the echars version I use now is echarts-4.2.0-rc.2.
    Trying to solve the problem, but too deep.

Can you provide the difference option between the normal and error chart?

你能提供正常和错误图表之间的差异选项吗？

谢谢，我已经找到问题，是在计算坐标时，y的值为NaN。从一开始我就找错了方向，因为坐标是随机计算的。并没有想到会是y值坐标出错。他们提示off没有定义。就直接进到错误代码行查找，最终没有结果。现在已经好了。
Thank you. I have found the problem. When calculating coordinates, the value of Y is NaN.

From the beginning, I found the wrong direction because the coordinates were random. I didn't expect it to be an error in the y value coordinate. They suggested that off was not defined. It goes straight to the wrong code line and finds no result. It's all right now.

但是，双击事件仍然无响应，代码见附件
a.zip
。
However, the double click event is still unresponsive, and the code is attached.

事件代码写法如下：
The event code is written as follows:

		g_myChart.on('dblclick', function (params) {
			console.log('dblclick');
		});
