SPC Chart Options

The SPC Chart Options window lets you configure charts to display on the current sub-inspection. For information on opening this window, see Setting charts to display in inspections.

Naming the chart group

When you first click New to create a group of one or more charts, you are prompted to name that group.

When editing the chart group, you can change this name.

Step 1: Select SPC standards for the retrieval

If you want this sub-inspection to chart multiple standards with the same chart types and chart settings, you can use this step to select all those standards at once – beginning with the Part Number Source:

When finished selecting standards, click Next Step.

Draw all charts in one panel

For this chart group, the Draw all charts in one panel check box sets whether to display each chart on a separate side panel tab or combine all of the charts on one side panel tab.

Display each chart on its own tab

Clearing the Draw all charts in one panel check box displays each chart on its own tab, like this:

If two chart groups with this setting draw the same chart type for the same information (SPC standard, Filter, and Date Period), only one side panel tab will be created.

Combine all charts on one tab

Selecting the Draw all charts in one panel check box combines all of the charts on one tab, like this:

When combining multiple charts on one tab:

Step 2: Select chart types

Select the SPC chart types you want to display, and then click Next Step.

Step 3: Modify settings for the selected charts

Choose retrieval and statistical settings for the standards and charts you have selected. You can also specify a Chart skin (created in the GainSeeker Charts module) that changes display options for these charts. When finished, click Save and Close.

If you want the charts to display the same data that is retrieved to calculate statistics (such as Control limits, Mean, R-bar, 2SD, and 3SD) for real-time failure checks, you should make sure the charts use the same Filter as the Numeric Input tests and use the default settings for Date period and Maximum count for retrieval. (The Default date period for SPC Data Entry and the default Maximum count for retrieval are both set in the System Administration module.)

Note: If you display a Statistics List or Statistics Table, GainSeeker will use the default report name from the current Chart skin (if specified) or from the current GainSeeker configuration. If a default Statistics list or Statistics table report name is not specified in either of these areas, GainSeeker will simply display system default statistics on these charts.

Tip: If desired, you can configure the charts with a special filter for data that matches traceability values in this inspection, as described below:

Filtering for inspection traceability values

In some cases, you may wish to filter the chart for a traceability value that was entered in this inspection – by a Traceability test in a previous sub-inspection or the current sub-inspection, a Planned Inspection, or a Formula test. If this chart group is linked to a Numeric Input test, any single-retrieval charts from the left-hand list can also filter for the TestSpecificTrace property on that test. (Multiple-retrieval charts from the right-hand list are not affected by TestSpecificTrace.)

For example, you might wish to filter for:

      • a Lot number that the user enters during data entry

      • a Machine ID that you preset with a Planned Inspection or Formula test

To filter for such a traceability value – which may vary from one data entry session to the next – you must create a Quick filter or a saved filter that looks for a blank value in that traceability field, such as this example which filters for the current Cavity number:

If this traceability value is not set before the sub-inspection with the filter is opened, the charts that use this filter will not be drawn until a value has been set for this traceability field. If this traceability value is cleared, the charts that use this filter will be removed.

Chart behavior during data entry

A chart will open when the sub-inspection opens and all information necessary to open the chart (SPC standard, Filter name, and Filter contents) has been defined.

Any chart linked to Numeric Input tests will be refreshed (the chart's data is re-retrieved from the database and statistics are recalculated) when there is a change to any of the information for the chart (SPC standard, Filter name, and/or Filter contents). Changing any traceability values that will be stored with the linked tests will also cause the charts to refresh. These changes can be triggered by the sub-inspection that created the chart or by a later sub-inspection that changes any of these values.

Submitting data for any linked chart will refresh that chart, unless that chart is linked to a Numeric Input test whose SPCStandardSelection property is set to DoNotStore.

Side panel charts will be closed when any of the information for the chart is removed, when a linked Numeric Input test is hidden (if chart is drawn only for that test), when the side panel is cleared, or when the inspection is closed.

The inspector can interact with the chart by clicking or right-clicking on the chart's background or graphics.
