SPC Control Chart Tools for Java

Version 1.6*

Add variable control charts (X-Bar R, X-Bar Sigma, Individual Range and Median Range charts), attribute control charts (p-, np-, c-, and u-charts), frequency histograms, and Pareto charts to Java based applications and applets using the SPC Control Chart Tools for Java.

X-Bar R Chart with integrated table support, frequency histograms, scroll bar and customize plot objects

The QCSPCChart SPC Control Chart Tools for Java software is an object oriented, Java based toolkit aimed at developers who want to add static and dynamic quality control charts to their Java applications. Typical users are SPC engineers and other quality control professionals creating .Java- 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 and Median Range 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). 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 Java available at any price.

*The Java version of QCSPCChart is still at Rev. 1.6 and at this time does not have new features added to the Rev. 1.7 version of the .Net version. These new features include EWMA, MA and Cusum charts, variable subgroup sample sizes, and visual alarm highlighting. These features will be added to the Java version of QCSPCChart by the end of June 2008. Any purchasers of the software will be able to upgrade for free to Rev. 1.7 at that time.

User Manual

Download Demo (615KB) - Run the demo by right clicking the downloaded QCSPCChartJavaDemo.jar file and selecting Open With -> (your standard Java runtime environment, javaw or Java 2 Platform Standard Edition Library for example). Or you can just run it from your browser by selecting Open from the browser File Download dialog.

Download Trial Version (16MB) - Unzip the downloaded Trial_QCSPCChartJavaR16x.zip file, preserving the directory structure. Run the Setup.jar program in the resulting \QCSPCChartJavaInstall directory using your standard Java runtime. Under Windows this can be done by right clicking the Setup.jar file and selecting Open With -> (your standard Java runtime environment, javaw or Java 2 Platform Standard Edition Library for example). This results in the software being installed in the \Quinn-Curtis directory. As a bare minimum read Chapters 1, 2, 10 and 11 of the manual, \Quinn-Curtis\java\docs\QCSPCChartJavaManual.pdf. Chapter 10 will have usage information with respect to the Eclipse, JBuilder and JavaBeans Java IDEs.

Key Benefits

	Fast development time because of the use of advanced templates for the most common SPC Control charts
	Charts have no limits on the number of data points or time frame
	Integrated histograms and tables displays require no programming
	Integrate with your database because the software is written and programmed using next generation programming language, Java.
	Add SPC charts to your web site by using Java Applet technology.
	There are no restrictions on what your program can do, since you can add any feature that you want using Java.

Feature Summary

	Java IDE Independent - Tested and compatible with Eclipse, JBuilder and NetBeans.
	Based on the Java Graphics2D API - Compatible with Java components and applications.
	100% Java Code - The software is entirely written in Java, resulting in provide better performance and scalability. Java code makes applications easier to deploy and maintain.
	Variable Control Chart Templates - X-Bar R - (Mean and Range), X-Bar Sigma, (Mean and Sigma), Median and Range, X-R (Individual Range Chart).

X-Bar R Chart (Mean-Range Chart)

I-R Chart (Individual Range)

Attribute Control Chart Templates - p-Chart (Fraction or Percent of Defective Parts, Fraction or Percent Non-Conforming), np-Chart (Number of Defective Parts, Number of Non-Conforming), c-Chart (Number of Defects, Number of Non-Conformities ) and u-Chart (Number of Defects per Unit, Number of Non-Conformities Per Unit ).

p-Chart (Percent Defective Parts, or Percent Defective Non-Conforming)

np-Chart (Number Defective Parts, or Number Non-Conforming)

c-Chart (Number Defects, or Number Non-Conformities)

u-Chart (Number of Defects Per Unit, or Number of Non-Conformities per Unit)

Other SPC Chart Templates - Frequency Histograms, Normal Probability Plots with probability scales and axes, and Pareto Diagrams.

Frequency Histogram

Pareto Diagram

Normal Probability Plot

Integrated Table Support - Sampled and calculated data values can be part of the SPC Control chart. Every sample subgroup has a pop-up notes text edit box where an operator can add observations.

Integrated Frequency Histograms – The variable control charts and attribute control charts can display a frequency histogram of the process variable side by side with the main SPC chart.

X-Bar Sigma Chart with frequency histograms and table support for calculated values

Customize Chart Objects - All of the plot objects created in the SPC chart templates are accessible to the programmer, allowing tremendous flexibility in the look of the SPC charts.

Customized backgrounds and plot objects

SPC Control Limit Calculations - SPC Control limits can be set explicitly, as the result of your own calculations, or the limits can be automatically calculated at 1-, 2- and 3- sigma levels using our own internal routines

Multiple SPC Control Limits – Control limits can be placed at 1-sigma, 2-sigma and 3 sigma levels for high and low SPC control limits.

Process Capability Ratios and Process Performance Indices – Automatic calculation and display of process capability ratios (Cp, Cpl, Cpu, Cpk and Cpm) and process performance indices (Pp, Ppl, Ppu and Ppk)

An X-Bar R chart with Cpk, Cpm and Ppk data displayed in the data table.

Variable SPC Control Limits – Control limits can either be fixed, and can vary with time.

Western Electric (WECO) Runtime Rules – The software will automatically calculate and process the alarm limits for the Western Electric Runtime Rules (WE 1, 2, 3 and 4).

An X-Bar R chart with that use Western Electric Runtime Rules.

Data Tooltips - Integrated data tooltips display chart data values in a popup window.

Median-Range Chart, with tool tip display

Integrated Scrolling - A scroll bar option permits the user to window in on 8-20 sample subgroups at a time, from a much larger collection of measurement data, representing hundreds or even thousands of subgroups, and move through the data, similar to paging through a spreadsheet. The scroll bar control can be used with static or dynamic SPC Charts.

	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.
	Data logging - SPC data values can be logged to disk in the CSV (comma separated value) format, for import into spreadsheets and other programs.
	Printing and Image Rendering – The SPC Charts, including the integrated tables, can be output to any Windows supported printer and Java JPG file.
	Java Documentation and Demo/Example Programs - The software includes a comprehensive 300 page user manual with many programming examples, XML help for every class. There are example programs for every chart type..
