Welcome to the community support forums !!
We are excited that you joined our OSS community. Please read about some of the FAQs in the community
The Psychart is a community plugin which means that we do not provide support for it as it is not maintained by us.
I check and founds its documentation page which might be helpful for you. Also, you can ask the question to your at their GitHub project.
I hope this helps.
