Bugfix

Fixes scaling error on control zone plots.

Adding Cpk plots with subgroups

Adding support for Cpk plots with subgroups.

Zone Control Plots Complete

• Zone control plots are now complete.
• Fixed a potential bug in which duplicated values may not have been noted on the zone control plot. This is now based on duplicated indexes, so the values are guaranteed to be shown.
• Examples are approximately up-to-date from an API standpoint.

API Overhaul

Changed API to be more consistent with community expectations for matplotlib and for six sigma terminology.

Better Zone Control Plots

Zone control plots with point highlighting for:

• beyond zone limits
• zone a violations
• zone b violations
• zone c violations
• trend violations
• mixture violations

Each of these can be individually turned off as well in order to more easily resolve overlapping violations on the plot.

Refining imports

Importing may now detect the limits directly from the header within the csv or excel file. The return type is also a dictionary containing the field names that are ready for analysis.

Adding Import options

• Adding import from csv
• Adding import from excel
• Slight tuning of cpk plot

Initial Release

Cpk plot looks great. Can install into jupyter notebook.
