Hi @ryan, you have two options to run your Custom Chart into the public Chartfactor Studio site, the easiest one is to enable the option “Load unsafe script”, in the way that shows the picture below:
And the second is to use a self-signed certificate registered on the Trusted Root Certification Authorities store, you can take a look at this article that explains this option very well: https://reactpaths.com/how-to-get-https-working-in-localhost-development-environment-f17de34af046. I hope this answer your question. Let me know if you have any problem. Best regards.
