to propose ChartDirector as an extension
I'm not a developper of ChartDirector ;-) but a simple user. I like it and use it on my clients websites. It would be nice to have it as an extension instead of having to install it manually.
At the moment we have no plans for creating an extension for ChartDirector. But you can create it by yourself with help of this documentation – https://docs.plesk.com/en-US/onyx/extensions-guide/plesk-extensions-in-a-nutshell.76331/
