Note, in particular, that previous versions of JMP had a more involved procedure for data entry, requiring rows to be initialized before use. JMP 4 adds rows dynamically as data are entered.
Screenshots were taken primarily in JMP 4.0.0. JMP 4.0.2 was used for "Shewhart p Charting," as version 4.0.0 contained a bug that prevented the creation of a standards-given p chart. If you are using a version later than 4.0.0, do not be alarmed at minor interface differences from the screenshots.
JMP is a product of the SAS Institute and is available for both Macintosh and Windows.
