WinChart® Standard and Professional

 

The Popular easy-to-use software for Statistical Process Control

WinChart® has been tailored specifically for Statistical Process Control, with more advanced features available in the Professional edition described overleaf.

WinChart® can also diagnose your control charts, looking for special cause variation (zigzagging, consecutive points above/below mean line, trends, points out of control, etc.)

WinChart® can produce control charts for different types of data:

  • Single measurements (XmR) charts (with moving ranges)
  • Subgroup (X-bar R) charts
  • Defects charts for fixed or variable intervals (c-, u- charts)
  • Defectives charts for fixed or variable intervals (np-, p-charts)

WinChart® now has the ability not only to import data from Excel/Lotus 123/Access databases - other formats can usually be supported as well on request - but also to check automatically if more data has been added! Other formatting such as labels, symbols, when a data entry is questionable ('?' marks), comments, and 'log numbers' for subgroup data (an identifying tag) can also be read.

Print up to 16 charts on a single sheet of paper!

If there are a large number of points then the chart can be displayed in two or more sections for easier viewing without affecting the statistical calculations (e.g. if you had 300 points then the chart could be displayed in 3 parts with 100 points in each).

In WinChart® all the calculations are based on Dr Walter Shewhart's original principles - unlike some SPC software!

WinChart® includes a Web Builder to allow the charts to be viewed in Internet Explorer (or similar web browser).

 

Features for the Professional Edition

 

These additional features are generally only intended for use by those who know Statistical Process Control well and who will not be tempted to "misinterpret" or "misuse" them!

WinChart® Pro also had these additional control charts:

  • Linear trend charts for single measurement data
  • CuSum (Cumulative Sum) charts
  • And for subgroup data:
  • Standard deviations chart
  • Moving mean
WinChart® Pro can now draw a histogram of the control chart - with the option to superimpose a normal curve o it and perform a statistical test for normality (for subgroup charts you can draw a histogram of the data as well):

Capability studies are available for single measurement and subgroup charts: Cp, Cpk, Z-Factor, and percentage out of tolerance for the process can all be calculated and displayed at the bottom of the chart.

A scatter plot can be drawn for two data sets, and the graphs of multiple data sets can be superimposed upon each other for comparison.

User defined reference lines can be shown on the chart for your own use.
