Highlighting the vital few and hiding the trivial many

Sometimes a few tweaks to highlight the vital few problems and hide the trivial many can lead to increased clarity of the plots.

  1. On the Analyse-it ribbon tab, in the Pareto group, click Reorder.

    The categories panel on the analysis task pane is displayed.

  2. To sort the bars on all plots into the same order:
    1. Select the Sort all by same key check box.
    2. In the drop-down list, select JDH.
  3. To move a specific bar to the end of the list:
    1. Select the Keep specific category at end check box.
    2. In the drop-down list, select Miscellaneous.
  4. To combine categories:
    1. On the Analyse-it ribbon tab, in the Pareto group, click Combine.
    2. In the Categories list, select Electrode failure.
    3. Hold down the CTRL key, and select Bulb failure.
    4. Click Merge.
    5. In the Name column, alongside the category in the edit box, type Equipment failure.
  5. Click Recalculate.

Miscellaneous problems are moved to the end of the Pareto plot. This is a sensible choice as this category comprises of all sorts of small unclassified issues that aren't of interest given the small amount of time they take up.

Problems are sorted into the same order as operator JDH who had the most total downtime making it easier to compare the plots.

Electrode failure and bulb failure are merged together into a new category named Equipment failure. These issues don't account for much downtime and resolving the problems isn't something achievable in-house without consultation with the manufacturer of the colorimeter.
