Multi charts select like in Google Cloud Platform

Question

I can create a single chart but I want to create multi charts that are selected all together when I hover over one of them, just like in google cloud dashboard : console.cloud.google.com/home/dashboard

If you go to the dashboard there is Compute Engine and API chart, if I hover to Compute Engine chart in the specific time, the both charts are selected at that time.

Update I found this one: http://jsfiddle.net/amcharts/PRQkG/embedded/result,js,html,css/

Answer 1

I have updated the fiddle you provided to make the following fiddle:

1. You need to merge two configs.dataProvider into 1 using

   for (var i=0; i<arrayA.length && i<arrayB.length; i++){
       arrayC[i] = {date: arrayB[i].date, val1: arrayA[i].value, val2: arrayB[i].value};}
   

Hope this helps.

2. you need to add entry for each series under config.graphs.
