How to resolve "Referenced error: Highcharts not defined" when using Easychart? I installed the Easychart module 7.x-3.7 in my Drupal 7.51 site. Using Highcharts 4.2.7 in libraries 7.x-2.3. I extracted highcharts and easychart-master contents into all/libraries/highcharts and all/libraries/easychart folders respectively. Easychart_ex and Chart contenttypes are shown when adding content.

However in my browser console I am getting this error:


  Referenced error: Highcharts not defined.


I tried all the suggestions mentioned in the Notes at the end of the answer to "How to plot a chart from CSV uploaded in a content type?", but none of them helped.

Is there any Easychart latest module I am missing or is it the way it is supposed to work (only with Highcharts 4.2.7) is a question left to Drupal!
Easychart 7.x-3.7 recommends version 4.2.7 of the Highcharts library. This is also what you can see in this specific commit.

And the Easychart project page states "... v4.x of the Highcharts library".

So it appears that using Highcharts 5.0.3 is not yet supported, which probably also explains the folder problems you described in your own answer. I don't think that you're missing anything else (or some other "latest" module) that you're missing (as long as you stick to the recommended version of Highcharts you should be fine).

PS: Be aware that there is also the feature request about "make use of new Highcharts 5.0.0 methods" (for the Easychart plugin).
