Interactive Plot Manipulation using Natural Language

no code implementations NAACL 2021 Yihan Wang, Yutong Shao, Ndapa Nakashole

This plotting model while accurate in most cases, still makes errors, therefore, the system allows a feedback mode, wherein the user is presented with a top-k list of plots, among which the user can pick the desired one.
