generic function or bapi for scheduling output ??

we are planning in a ztable periods for persons on different projects.

now we want to report this in a schedule graph like manner as a normal planning board would look like. (so 1 person can be visible in different periods in 1 line if he is planned in different periods)

are there generic functions where you can create such output with ??

I hope my question is clear otherwise don't hesitate to ask

kind regards
