QCSPCChart CF - SPC Control Chart Tools for .Net Compact Framework

Version 2.0 - Special Note - QCSPCChart for .Net CF is at Revision 2.0 and does not include the following features found in the other version of this software: Named rule sets (Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan), MAMR, MAMS and DPMO charts.

Add variable control charts (X-Bar R, X-Bar Sigma, Individual Range, Median Range, EWMA, MA and CuSum charts), attribute control charts (p-, np-, c-,  and u-charts),  frequency histograms, and Pareto charts to .Net Compact Framework applications using the SPC Control Chart Tools for .Net CF.

The Quinn-Curtis SPC Control Chart Tools for .Net Compact Framework (QCSPCChart CF for short) software is an object oriented, .Net CF based toolkit aimed at developers who want to add static and dynamic quality control charts to their C# and Visual Basic for .Net Compact Framework applications. Typical users are SPC engineers and other quality control professionals creating .Net based applications that will be used to monitor critical quality factors in manufacturing, process, and service industries. The feature rich toolkit includes templates for the most common SPC control chart types: variable control charts (X-Bar R, X-Bar Sigma, Individual Range, Median Range, EWMA, MA and CuSum charts), attribute control charts (p-, np-, c-,  and u-charts), frequency histograms, probability charts and Pareto diagrams. The software will automatically calculate SPC control limits using historical data for the supported variable control chart and attribute control chart types. Alarms can be generated for standard +3 sigma control limits, or the Western Electric (WECO) Runtime Rules (1, 2, 3 and 4). Alarms can be color highlighted in the SPC charts and table.  It will also calculate process capability ratios (Cp, Cpl, Cpu, Cpk and Cpm) and process performance indices (Pp, Ppl, Ppu and Ppk). Users are able to interact with charts: adding annotations, defining custom tool-tips and editing notes. There is no comparable product for .Net CF available at any price.

It is very difficult to make SPC chart displays small enough to fit on the Windows Mobile, PDA, PC Phone, and other emulators that ship with Windows Visual Studio. Those emulators have tiny, tiny screens. While it is possible to run this software on small screens, it is assumed you want this software to run on dedicated Windows CE devices with a minimum screen resolution of 640 x 480. If you already have hardware that meets this requirement, you can use your actual hardware device as your development environment. If you have an emulator for your hardware (usually supplied by the hardware manufacturer as part of a development kit they sell), you can use that. All of the images on this page were create using a generic, standalone, Windows CE 5.0 emulator from Microsoft, set to a screen resolution of 800x600. It can be downloaded from Microsoft here: Microsoft Windows CE 5.0 Emulator.

Revision 2.0 adds new options for labeling of the tick marks in batch control charts: time stamp labeling and user-defined string labeling, in addition to the default numeric batch number labeling. Also, x-axis labels can be rotated 360 degrees. Since QCSPCChart is built on top of the QCChart2D software, there are many new features associated with Revision 2.0 of the QCChart2D CF software.

bulletAuto-Scaling - The y-axes of the SPC charts can be auto-scaled to display all data and control limits, or the minimum and maximum value of the y-axis can be explicitly set.
bulletControl Limit Alarm Events - Alarm events can be triggered whenever a process variable exceeds an SPC control limit.

New Alarm Features -  There is a new status line in the table section that gives a direct indication of whether or not the corresponding process variable is in, or out of, alarm. The status line has a tooltip, so if you click on an alarm, a pop-up box will show you details. Optionally, the entire column associated with a sample interval can be color highlighted to indicate an alarm condition. Alarm details can be automatically logged to the notes log. The symbol used to plot a process variable point in the primary and secondary charts can be made to change color in the event of an alarm.

bulletData logging - SPC data values can be logged to disk in the CSV (comma separated value) format, for import into spreadsheets and other programs.
bulletVB and C# Documentation and Demo/Example Programs - The software includes a comprehensive 300 page user manual with many programming examples, XML help for every class. Every programming example and example program is presented in C# and Visual Basic.


QCSPCChart CF for .Net Compact Framework Limitations

bulletDue to the constraints (processing power, memory, display resolution, printer support) of mobile devices, the .Net Compact Framework is a subset of the regular .Net runtime system used on workstations. These limitations restrict some of the features implemented in the QCSPCChart CF software.
bulletBrushes - The .Net Compact Framework Brush class is also very basic. Brushes have only a color attribute, no texture or gradient brushes are included.
bulletColor - The .Net Compact Frameworks color model does not support alpha blending so transparent colors are not possible.
bulletPrinter Support -The .Net Compact Framework does not support printer output.
bulletCoordinate Transformations - The .Net Compact Framework does not support the coordinate transform routines found in the .Net System.Drawing.Drawing2D classes. As a result, text and bitmap images used in charts cannot be rotated.
bulletImage Output - Charts cannot be saved as image files.


QCSPCChart CF for .Net Compact Framework Developer Licensing

bulletOur license agreement can be found here.
bulletThe QCSPCChart CF for .Net Compact Framework Developer License is available in a Developers Version (model # NETCF-SPC2-DEVR) that does not time out. Free updates for two years. The Developers Version of the  QCSPCChart CF software includes the QCChart2D CF software and there is no need to purchase QCChart2D CF separately.
bulletThe QCSPCChart CF for .Net Compact Framework Developer License is licensed to a single individual. It cannot be used by multiple people at the same company, unless a separate license is purchased for each person. Site licenses are also available. Contact sales@quinn-curtis.com with details of how many seats you wish to purchase and we will respond with a quote.
bulletThe QCSPCChart CF for .Net Compact Framework Developer License software does not use a redistributable license,  unlike the previous versions of the software. The basic developer license permits you to include QCSPCChart CF  as part of your application and distribute an unlimited number of copies of your application, royalty free.


QCSPCChart CF for .Net Compact Framework Redistributable Licensing

bulletThe QCSPCChart CF Tools software does not use a redistributable license. The basic developer license permits you to include QCSPCChart CF as part of your application and distribute an unlimited number of copies of your application, royalty free. We do not allow developers to use this software to create a graphics toolkit (a library or any type of graphics component that will be used in combination with a program development environment) for resale to other developers.


Custom Programming Services

bulletThe QCSPCChart CF SPC Control Chart Tools for .Net Compact Framework is an extremely powerful and flexible software package. It contains over 1000  methods and properties in more than 120 classes. The user manual and  help file documentation are more than 1500 pages. This can be overwhelming to the average programmer who wants to start programming today and have the prototype of an application working in a week.
bulletThe variety of user interfaces for charting applications is as diverse as the industries using the software. The end-user of an application at a drug company expects to interact with the chart in a manner different than that of an end-user in the automotive industry.
bulletWe know that your application may be similar to, but still uniquely different from any of our example programs. To that end we offer our programming services to write for you a custom example program that demonstrates how to code the chart format and user interface you want. That jump start to your project can save you many weeks of work and make you look like a chart programming genius. All  you have to be able to do is describe in detail what you want the example to do.
bulletUsing QCSPCChart CF, our range of expertise includes Managed C++ (MC++), C++/CLR,  VB, and C#  programming languages. For more information or a quote, please contact our sales department at sales@quinn-curtis.com
