My previous PI used my data in an article that was published in a high profile journal. My name is nowhere to be found in authors list
Creating the graphs and tables for a paper does not necessarily entitle you to authorship (https://publicationethics.org/files/Authorship_DiscussionDocument.pdf).  But creating those graphs and tables nearly always requires some other activity that does entitle you to authorship.  Your work should be acknowledged at a minimum.
If you are entitled to authorship based on the standards of your field, you may:

Request that the professor ask the journal for a correction of the author list.
If that fails, request that the journal retract the paper for plagiarism.
