External Data Links with Drill-downs and ‘Dicing & Slicing’

You have SPC software? You have six sigma software? You have fantastic statistical packages?

… but do you have your data?

Winchart Discovery

Once the ‘top level’ chart has been created from your source data then, as illustrated in the diagram above, there are various features:

  • WinChart can automatically scan your source columns and make a suitable chart for your selection.
  • The charts can be viewed monthly, weekly, or daily – all with a few simple clicks.
  • Percentage calculations can be performed without cumbersome SQL queries or data manipulation.
  • Regularly-used charts can be made from a dataset in one go, thus leaving the drill-down feature to be used only when required and making such charts quickly and easily accessible.
  • Sometimes it takes time for a data set to be up-to-date. WinChart can easily handle this by allowing points within a specified number of days to be marked as incomplete or to be omitted.
  • All without needing to contact the ICT department each time!

Additionally, when 'slicing and dicing' data, abbreviations in the source field names or in their entries can be replaced by more meaningful descriptions. Charts will be updated automatically from the source data on opening, however an ‘update delay’ can be used, allowing charts to be accessed many times within a short time period without needing lengthy re-reading times. (Access, Excel, MS SQL, etc. supported.)

Significant Points are Highlighted Automatically

As can be seen in the cyclic control chart, significant points and runs of points are highlighted to bring them to your attention.

significant points


  • The orientation
         up = ‘good’ = green,
         down = ‘bad’ = red,
         both up/down = ‘bad’
    can be changed per chart
  • The colours used can be changed
  • Can be turned off if required


Process changes (‘splits’) can be included


    • Limits can also be fixed/unfixed
    • User text can be added on the chart as desired
    • Longer comments can be stored per point
    • Rogue points excluded from calculations if desired

Long charts can be partitioned

Partitions ‘cut’ the chart, each part ‘stretched’ for greater readability. The most recent partitions can be set to have a fixed number of points in each.
