I really do think that all the ways that the plot package makes J crash or hang for the slightest mistake is a major drawback.
JVERSION Engine: j903/j64avx2/darwin Release-b: commercial/2022-01-28T04:20:11 Library: 9.03.08 Qt IDE: 1.9.5/5.15.2(5.15.2) Platform: Darwin 64 Installer: J903 install InstallPath: /applications/j903 Contact: www.jsoftware.com load 'plot' ('xlabels ',":i:10) plot i:10 NB. should have been "xlabel" (goes on forever, have to force J to quit) In J playground: load 'plot' ('xlabels ',":i:10) plot i:10 |option not found: xlabels: signal | signal'option not found: ',j |[-0] Much better.
