EDIT 2: I found this article and created a .htaccess file in the root dir of my site in wamp with the following two lines:
AddType image/svg+xml svg svgz
AddEncoding gzip svgz
But still no errors and no charts. Could it be a WAMP set up issue? As I said this code works on my online site...
EDIT: I placed an "alert(d.max_energy)" in the code and I can see the JSON values returning to the client page. It just does not get processed into a chart nor complain with an error.
I am sure this is a simple fix but I cannot see it. I have the following code on a hosted site which works OK, and have now replicated in WAMP local server (a different machine in my network from the development PC), but does not execute / cause an error in Console / Inspect.
Any help is appreciated.
