Add variable control charts (X-Bar R, X-Bar Sigma, Individual Range, Median Range, EWMA, MA, MAMR, MAMS and CuSum charts), attribute control charts (p-, np-, c-, u-, and DPMO charts), frequency histograms, and Pareto charts to .Net and Asp.Net applications using the SPC Control Chart Tools for .Net.X-Bar R Chart with integrated table support, frequency histograms, Cpk and Ppk statistics, scroll bar and customize plot objects
The QCSPCChart SPC Control Chart Tools for .Net software is an object oriented, .Net based toolkit aimed at developers who want to add static and dynamic quality control charts to their C# and Visual Basic for .Net 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, MAMR, MAMS and CuSum charts), attribute control charts (p-, np-, c-, u-, and DPMO-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 standard SPC rule sets (WECO, Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan). 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 available at any price.

- Visual Studio .Net 2015 and higher – Starting with Revision 3.0, we have eliminated support for Visual Studio .Net 2005 through 2013. This way we no longer have to configure the libraries for the lowest common denominator of .Net, and can use new .Net features not found in original version. The software is compatible with Visual Studio .Net 2015, and higher. All example program projects are in Visual Studio 2015 format, and automatically convert to Visual Studio 2017 format when loaded using that compiler. The standard DLLs are compiled for a target of .Net Framework 4.5.1. This means it should be compatible with programs written with that target or higher. There are no legacy dependencies associated with the .Net 2.0 runtime libraries.
- Windows 32-bit/64-bit Compatible – The software will run as 32-bit on Windows 32-bit operating systems (XP and later 32-bit versions of Windows) and as 64-bit on Windows 64-bit operating systems. This is a feature of programs and libraries written using .Net (Version 2.0 or greater) in general.
- Based on the .Net Drawing and Drawing2D API – Compatible with .Net components and applications.
- 100% Managed .Net Code – The software is entirely written in C#, resulting in provide better performance and scalability. Managed .Net code makes applications easier to deploy and maintain.
- New Features in Revision 1.7 – New variable controls charts (EWMA, MA and CuSum), additional charts support variable subgroup sample sizes, alarm emphasis modes for the the tables and charts, and elimination license file, and the need to purchase redistributable licenses.
- New Features in Revision 2.0 – 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 software.
- New Features in Revision 2.2 – support for Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan rule sets in addition to the WECO rules. Exisiting rules can be customized, or new rules created using templates. Added MAMR (Moving Average / Moving Range) and MAMS (Moving Average / Moving Sigma), DPMO (Defects per million) charts. As an aid to internationalizations, all of the default (US English language) strings have been moved into a single static class, where they can be initialized at runtime with country specific values.
- New Features in Revision 3.0 – added a Levey-Jennings variable control chart. All charts have been converted to use EventCoordinates. A zoom control can optionally replace the integral scroll bar, permitting the user to customize the x-scale of the display. Toggle buttons can be used to turn on/off the display of the table rows. Enhanced annotations and out of limit symbols. Bad sample interval marking. For a complete list, see this summary sheet: Rev. 3 New Features

- Integrated Zooming -The horizontal scrollbar can be replaced (toggled on/off actually) using the UI, with a zoom window, by clicking on the z-button in the lower right corner. The user will be able to scroll the charts by dragging the transparent blue zoom window left or right, or expand the x-axis scale by dragging the left or right edge of the zoom window.
Use the mouse to scroll the charts by dragging the transparent blue zoom window left or right, or expand the x-axis scale by dragging the left or right edge of the zoom window.
|If you use the zoom window to display a lot of points, the table at the top will disappear to prevent the table columns from overlapping.|
- Dynamic Updates of SPC Charts – SPC Charts can be updated and control limits re-calculated in real-time.
|Dynamically updated X-Bar R chart with variable control limits|
- Auto-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.
- Control 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.
- Data logging – SPC data values can be logged to disk in the CSV (comma separated value) format, for import into spreadsheets and other programs.
