graph 加载数据,产生off未定义错误

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

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. 
a.zipFrom 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: ```javascript g_myChart.on('dblclick', function (params) { console.log('dblclick'); });
