Well\u2010known methods include star coordinates or principal component biplots, which represent data attributes as vectors that define axes, and produce linear dimensionality reduction mappings. In this paper we propose a hybrid approach that bridges the gap between star coordinates and principal component biplots, which we denominate \u201cadaptable radial axes plots\u201d. It is based on solving convex optimization problems where users can: (a) update the axis vectors interactively, as in star coordinates, while producing mappings that enable to estimate attribute values optimally through labeled axes, similarly to principal component biplots; (b) use different norms in order to explore additional nonlinear mappings of the data; and (c) include weights and constraints in the optimization problems for sorting the data along one axis. The result is a flexible technique that complements, extends, and enhances current radial methods for data analysis.<\/jats:p>","DOI":"10.1111\/cgf.13196","type":"journal-article","created":{"date-parts":[[2017,7,4]],"date-time":"2017-07-04T15:14:58Z","timestamp":1499181298000},"page":"389-399","update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Adaptable Radial Axes Plots for Improved Multivariate Data Visualization"],"prefix":"10.1111","volume":"36","author":[{"given":"M.","family":"Rubio\u2010S\u00e1nchez","sequence":"first","affiliation":[{"name":"Universidad Rey Juan Carlos  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Sanchez","sequence":"additional","affiliation":[{"name":"Universidad Rey Juan Carlos  Madrid Spain"},{"name":"Center for Computational Simulation  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.
