It’s possible if you create separate table for each user. You’ll need to fill the table with default values, e.g. 0. Otherwise the chart won’t be created.
Our plugin allows editing frontend fields by logged in users only, we don’t have specific form for this.
Note that our tables don’t allow restrict access to specific user.
I can check with our developers if this can be implemented. Please contact us through our internal support and send us detailed description of what you need.
