Hi,  
As you can see on this exemple :  
https://codepen.io/heexos/embed/preview/Pomwmbq?default-tabs=js%2Cresult&height=300&host=https%3A%2F%2Fcodepen.io&slug-hash=Pomwmbq  
The double click is not working on this kind of exemples. I got 2 traces, that I display depending on the selected option with the buttons. The 2 traces has some data in common.  
Some of my tests even append a “undefined” in hiddenlabels, but i can’t reproduce that in codepen, maybe a browser specific issue…  
Does someone has a fix for that?  
Thanks !
