A collection of simple files to quickly produce meaningful charts for Statistical Process Controll (SPC). It relies mostly on the great Plotly graphics library to present the results.
The additional statistics in some files is mostly knowledge I gathered and used in praxis from a Six-Sigma Black Belt course. For the rest, I do not remember where I snatched it.
The general workflow is to load the file in a browser, and dump data into a textfield. The format can be quite free. If a file requires keyed data, like the multi-box-plot, the first element must be the key. The next elements are separated by tabs, or by semicolon. Tabs are for copy-paste from Excel, semicolons for human input. For one key, there can be multiple values in one line. If a value is not present or cannot be parsed, it is ignored.
The exception to this rule is the multi-scatter plot, whis one requires key, x, y in one line.
In order to be able to run this also offline, I have added foreign
libraries into the directory js. These are
- The graphics stuff, Plotly
- Data Driven Documents, D3
- Some statistic from Fast Statistics
- sprintf
- Some distributions were taken from Thomas S. Ferguson
