Can’t load data from external file
How can this be of any value if you cannot load data from an external file?! Loading one by one is .... excruciating. I’m using the free version. If this is an artifact of the free version, they should disclose that in the app narrative.
Response from developer
The program has always been able to load/save the chart setup, and data, from an external file (up to 100 sample intervals for the Free Version). This feature is accessed from the Setup | File menu. For IOS it is documented on pages 35-38 and 43-46 of the online manual. IOS doesn't make it easy getting data files on and off a tablet but it can be done using the procedure described in the manual. "File transfer" is found in the index.
Excellent for charting analytics
Worth paying for the commercial version (low cost btw) for serious statistical process control or analytics app development. However, free version is very handy for learning the SPC Chart tools. If you are in the business of proving six sigma compliance of your quality control then these tools will allow you to show off your data using all the standard methodologies.
