Independent series and different plotter functions

[Hugoer]

Hello! I think there is a problem when we are working with more than one series, and we want to indicate more than one different "plotter". I have tried to indicate it in the series, and in the general options to discard that it is the own function that modifies the plotter, but if you observe the two jsfiddle that I attach, and changing the commented code, you will see that a strange situation takes place. If the points are displayed, but lines are not formed correctly between them. I tried looking for the open issues, debugging the library (but it's too complex for me).

Multiple independent series:

Same code but only one serie:

Filing a bug report? Please include the following:

I am using windows 10, Ionic 3 project and node 8.9.3, But I think it is indifferent to reproduce this possible error. Same situation on chrome, firefox, edge, also on iOS (chrome, safari and firefox), always same situation.

Dygraphs version is 2.1.0

I am also adding "http://dygraphs.com/src/extras/smooth-plotter.js"

I hope this is enough information so that you can debug. If you need me to develop more tests, situations or different casuistry, do not hesitate to tell me and I will try it.
