I want to send email with diagrams to the email body in php, but I do not receive.
I tested some methods, for example google graphic cards (outdated), google charts, jqgraph, but without success.
One solution would be to create a static image generated on the server and send that image to your email address. The ZingChart javascript chart library provides a special assembly for working with the PhantomJS headless server browser, which allows you to create chart PNG images, http://www.zingchart.com/docs/features/phantomjs/
I am part of the ZingChart development team, so let me know if you have any questions.
